Collaboration

We cannot do all of it ourselves.

Bamboo, batik, khat — three skills that are not ours, done by people who genuinely command them. This is the record of who has worked with us, and how to propose the next one.

Where we stand

What we do, and what we do not

Hibrkraft works leather, paper, thread and binding. That is all. Whenever an order calls for a skill outside those four — weaving bamboo, batiking cloth, writing khat — we find someone who does it every day, and we print their name.

Not out of politeness. If a book is covered in Handayani batik, what makes that cover good is Handayani, and the buyer is entitled to know. The practice is simple: the partner does their part, we do ours, and their name travels with the story.

What we bring: Leather, binding, hand sewing, laser engraving, and access to corporate buyers.
What we look for: Material skill we do not have, worked by the partner themselves — not imported finished goods waiting for a label.
Scale: From a single prototype to a corporate order in the hundreds. There is no minimum for starting a conversation.
Attribution: The partner is named on the product page and here. We do not sell other people’s work as our own.

Already running

Three that have been made

Every photograph below is of work that was actually made. No renders, no supplier catalogue shots.

01 — Bamboo

Sagala Tina Awi

Aban · bamboo instruments & souvenirs · West Java

A bamboo artisan sitting in a woven-walled workshop, shaping a pen body, surrounded by flutes and bamboo tubes

Sagala Tina Awi — Sundanese for “everything from bamboo” — makes flutes, tumblers, tableware and pen bodies from bamboo he selects and shapes himself. The workshop walls are woven; the tools are hands.

What we made together is a pen. The body is Aban’s, the laser engraving ours, and the result is paired with a leather book as a set. A bamboo pen cannot be machine-made: every internode differs in diameter, so each length has to be measured one at a time.

A bamboo pen with its cap off, on a green cutting mat — Body and cap, before engraving.

Close-up of a bamboo pen lettered Sagala Tina Awi, Alat Musik & Souvenir — His own mark, not ours.

A bamboo pen on a freshly laser-engraved sheet of leather, beneath the engraver head — Our part: the leather, and the engraver.

A row of shaped bamboo pen tips, lined up against a ruler — Every internode differs, so each is measured on its own.

Several bamboo tumblers standing and lying on hessian cloth — Another of Aban’s lines: bamboo tumblers.

02 — Batik

Handayani

Batik cloth · cover material supplier

A notebook covered in red and black batik cloth, held above mossy stone — The cover is Handayani cloth.

The same book from the side: a sewn text block, edges painted orange, a black elastic tie — Inside: a hand-sewn block, painted edges, black elastic. That part is ours.

Patterned cloth is a difficult covering material: the motif has to land in the right place once folded, and cloth moves while it is being glued where leather does not. The two photographs above are paired deliberately — one shows the cloth, the other shows what is behind it.

03 — Khat & calligraphy

Pak Munawir

Beladuarna · khat and calligraphy · hand-painted

A round wooden medallion framed in deep red, the Hk monogram hand-painted on a yellow field

The Hk monogram in that photograph is not printed. The frame is turned, the field is painted, and the letters are hand-painted by Pak Munawir of Beladuarna — whose daily work is khat panels measured in metres, not company logos.

We went to him because hand-painted lettering has something no vector can imitate: the weight follows the pressure of the brush, and no two are exactly alike. For a maker selling hand-sewn books, a machine-printed logo rather contradicts the story.

From the archive — old photographs, at whatever resolution they came

Pak Munawir standing beside a large calligraphy panel against the sky — Pak Munawir, undated.

The artist crouching over a black, gold-framed calligraphy panel inside the workshop — A large panel, worked on the workshop floor.

The artist painting calligraphy on a red and green oval medallion with a fine brush — An oval medallion, worked with a fine brush.

From the archive

Two brand collaborations, 2016 and 2017

These two are a different kind from the three above. Not a material skill we brought in, but another brand making its own product while we made the book — one product, two names. Both are old, and one of them never reached the market at all. Both are written up here because a collaboration that failed is also part of the record.

Archive 2016 — Cake

Bananagasm

Banana cake · a bundle that was planned · never released

Bananagasm sold banana cake in yellow boxes. The plan was a single bundle: their cake, our notebook — one gift of which part is eaten and part is used for years.

The bundle was never released. The brand stopped first. All that survives of the plan is these photographs, taken on 14 May 2016, and they stay here as they are.

Two hands writing in an open journal with kraft-coloured pages on a wooden table, a yellow Bananagasm box and a cup of black coffee above — Our book, their box, one table.

A tan leather journal tied with a strap, cross-stitching visible along its spine, beside a card printed with a bird, a gold pen and a yellow Bananagasm box on a light brown surface — The cross-stitch shows along the spine.

A flat lay on kraft paper: a brown leather clutch with a brass clasp, a pocket watch on a chain, glasses, a phone with earphones, cards, a leather journal with a tie, a green notebook and a yellow Bananagasm box — How 2016 photographed a plan: laid out on kraft paper.

Archive 2017 — Notebooks

Goodnote ID

GN.ID · travel journal · where Trevi came from

Two Trevi journals side by side, one teal and one red, each closed with an elastic cord and stamped with two small logos at the lower corner of the cover

Goodnote ID — GN.ID — made the notebooks; we made the leather covers. That partnership produced Trevi: a refillable travel journal, one leather cover holding inserts that can be swapped and added to on elastic cords.

The cover carries two marks side by side, Hk and GN.ID — not one brand riding on another. This generation of Trevi is no longer made; Trevi-2 replaced it. The photographs are from April and May 2017.

Close view of a red leather cover with two square stamps side by side: Hk and GN.ID — Two marks, level, the same size.

A kraft paper cover printed with the Eiffel Tower, a Union Jack and postal marks, stamped Hk Hibrkraft, with notebook inserts and coffee beans around it — A paper cover printed with travel marks, stamped Hibrkraft.

A Trevi journal opened to show interchangeable pink and teal inserts held on elastic cords inside a red leather cover — The inserts come out — that is the whole idea of Trevi.

From the archive — 2017 promotional material

A 2017 promotional card reading Friendship That Becomes A Collaboration and HK times GNID, over a photograph of teal and red leather journals — The promotional card, as it was.

Three notebook inserts in orange, sage green and tan, labelled Note Book, arranged on a dark wooden table with coffee beans — The inserts themselves, before they go into a cover.

Our travel-journal story in 2016–2017 has a side to it that does not reflect well on us, and we have written that up ourselves, apology included, to the maker we left mid-conversation: The ghosts of unfinished chapters — a prototype from 2016. This page is not complete without that one.

Propose a collaboration

Fill in what you can. We really only need three things: who you are, what your skill is, and what you are proposing. The rest may be left blank.

JavaScript is switched off. The form above composes its message with JavaScript, so the button will only open an empty conversation. Write straight to WhatsApp on +62 815 1119 0336 or email admin@hibrkraft.com instead, giving your name, your skill and your proposal.

Other ways

Email — admin@hibrkraft.com. Use this if you have attachments: a portfolio, sample photographs, or a quotation.
WhatsApp directly — +62 815 1119 0336, if you would rather type it yourself.
Come by — our workshop in Bogor. Let us know first through one of the routes above, because there is not always someone in.

After you send it

1We reply, sooner or later. This is an inbox read by a person, not an automated ticket. If you have heard nothing after a week, ask again — most likely it was missed, not refused.
2We ask to see the work. Photographs, a physical sample, or a visit. What we are looking for is work you genuinely do yourself.
3One prototype first. Nearly every collaboration on this page began with a single object made to see how it turned out, not with an agreement.
4If it works, we print your name. On the product page and on this one.

Frankly: we cannot take on every proposal, and the ones that most often come to nothing are those asking us to resell finished goods. If that is the aim, say so at the outset — so that nobody wastes their time.

Not sure your idea fits?

Just ask first. No proposal needed.
