A3 Set
A3 Set
Three rewritable sheets, 42 × 29.7 cm each
An A4 sheet tempts you into lists, A3 invites you to draw: big enough for a thought to spread out, small enough for any table. Three sheets mean three projects running in parallel, or one for each person at the table.

Add pens
Comes off again with a barely damp cloth. The most convenient pen for Infinity Stonepaper. Other pens come off too, they just need more water and a little rubbing.
We carry pens as a companion to the stone paper, rather than as a range of their own.
How it works
Write on it. Wipe it. Next.
Write on the sheet with erasable pens. As long as the project runs, everything stays. When it is done, water dissolves the writing and the same sheet carries the next topic.
Three sheets
Room for mind maps.
An A4 sheet tempts you into lists, A3 invites you to draw: big enough for a mind map, small enough for any table. Three sheets are three projects running in parallel, and folded once each of them becomes a booklet with four pages.
A surface for getting from your head onto the sheet without knowing in advance where it will go. Whatever turns out to be wrong gets wiped away, the rest stays.
One topic in the middle, the branches around it. Whatever shifts gets wiped away and set anew, and the map of the project stays the same for weeks.
Fold it once down the middle and you have four writable pages. The topic on the front, room for details inside. Handy for field trips, minutes and anything with a sequence.
One sheet each and another in the middle. Or three stations around the room, all of them empty again at the end of the day.
Rolled up in the carrying tube, the set fits in any rucksack. On the train the sheets go onto the window with a little water, and there is your working surface. Outdoors, permanent pen holds most reliably.
Material and facts
The material in brief.
Stone instead of pulp, usable again and again. What the sheets are made of and what that means for handling them.
What you get
3 A3 sheets measuring 42 × 29.7 cm and a carrying tube.
Composition
Two thirds limestone, a by-product of quarrying, one third HDPE, partly from recovered material.
450 g/m²
Stronger than ordinary paper. Made in a dry process: no wood, no process water, no chlorine bleaching.
Waterproof and tear resistant
The surface does not absorb, the colour sits on top and can be taken off again. Grease and rain do not bother the sheet.
Assembly and shipping
Cutting, rounded corners, packing and shipping are handled by the Christophorus Inklusionswerkstätten in Fürstenwalde, Germany.
When a sheet has served its time
Most of the time it has not. If you do take a sheet out of circulation, you can carry on using it: fold it, cut it, glue things onto it. The material works well for origami.
Good to know
Frequently asked questions
What can A3 do that A4 cannot?It invites you to draw instead of to list.
A4 is the size of a page, and on a page you write lists. A3 is twice as big, so you start to sketch, to connect and to cluster. On top of that, A3 can be folded once and becomes a booklet with four pages. If you only want a surface for notes next to your computer, A4 is the cheaper option.
What is the difference from the Infinity Folder?Three identical sheets instead of three formats with a backing board.
The A3 set consists of three sheets of the same size in a tube, meant for parallel surfaces and for sharing. The Folder contains mixed formats, 2 × A3, 2 × A4 and 1 × A5, plus a firm board you can write on without a table. If you need surface for several people, take the set. If you need a workplace for when you are on the move, take the Folder.
How do I turn a sheet into a booklet?Fold once down the middle, four pages.
Fold the sheet down the middle to A4. Then you have four writable pages: the topic on the front, room for details inside. The material does not crack when folded, and later the sheet can be spread out flat again and used as normal.
How do I get the sheets flat after unpacking?Just roll them the other way.
The sheets come rolled up in the carrying tube. Roll them briefly in the opposite direction and they lie flat. On the table they soon settle by themselves under their own weight.
How do I get the sheets onto the wall?Water for glass, otherwise pins or tape.
On glass, windows, mirrors and whiteboards the sheet holds by adhesion: dampen the back, press it on, done. On the train the window becomes a working surface this way. On rough walls pins or tape work, the material does not tear out.
Which pen do I use?Thermosensitive ink or water-based felt tip.
Two groups come off again. Thermosensitive ink dissolves with very little water, a barely damp cloth is enough, and it writes fine. Water-based felt tip pens are stronger in colour and readable across the room, but they need water and some rubbing. Whiteboard markers and permanent pens stay for good. With four colours you can keep layers apart without the surface becoming restless.
Can I put the sheets in my printer?Definitely not.
No. Stonepaper does not tolerate the heat in a laser printer, and in an inkjet printer the ink does not soak in. Both damage the device. The sheets are made for writing and drawing by hand.
Can I cut the sheets to size?Yes, with scissors.
Tearing is hard, cutting on the other hand is easy. If you need smaller formats, cut them to size, the edge does not fray. Punching holes works too, the material does not tear at the hole.
What do I do if there is no water when I am out and about?A dampened tissue is enough.
Thermosensitive ink needs hardly any moisture. A lightly dampened tissue is enough to clear a surface again. For larger surfaces water is more convenient.

In use
From the desk to the window
On your own at the desk, seven of you around a board, on the window, outdoors on a branch. And in the end as a photo on your computer.
Material and handling
Cleaning, sticking, durability
The colour does not sink in, it sits on top. Water dissolves it, the first time and the hundredth. Dampen the back and the sheet holds on any smooth pane.
