Infinity Stonepaper
Smart bookmarks: how Cards and Notes deepen your reading
A good book delivers plenty of impulses. To keep those impulses, it helps to have a fixed place for notes: the Infinity Stonepaper Cards and the more compact Infinity Notes. On them you gather thoughts, hold on to ideas, carry them over into your own context and then put the content into practice.

Both formats are made of stone paper: write on it, wipe it, write on it again. That turns every reading experience into a personal store of knowledge and leaves the book itself clean.
How and where you can use them
- Reading specialist and non fiction books: hold on to insights while you read.
- At school and university: structure content and create summaries.
- In creative writing: visualise thoughts, characters and scenes clearly.
- For discussions and book circles: bring questions and ideas for each chapter.
- For self reflection: journaling, vision boards and collections of ideas.

Cards or Notes: the right format for every book
The larger Cards (12.75 x 18 cm) offer room for summaries, mind maps and outlines. The handy Infinity Notes (12.75 x 9 cm) suit quick flashes of insight. They fit into paperbacks, serve as a smart bookmark and catch single thoughts for each chapter.

How it works, step by step
- Write down content in your own words as you read.
- Photograph sketches and drawings.
- Digitise the content (through speech recognition or with a language model, for instance).
- Write the last thought at the top of the card and place the card in the book.
- Wipe the card and keep it ready for the next ideas.
This is an elegant way to take exactly those things out of a book that count for you.

Every reading experience becomes a personal store of knowledge.
The material at a glance
The stone paper is made of 60 percent calcium carbonate and 40 percent HDPE. It is produced in a dry extrusion process. At 450 g/m² the cards stay tear resistant and waterproof, and the surface is wipeable and rewritable. The material carries Cradle to Cradle Certified Silver. At the end of their working life the cards belong in the residual waste.
The two formats in the shop
The Infinity Stonepaper Cards come as a set of 10 (12.75 x 18 cm), the Infinity Notes as a set of 20 (12.75 x 9 cm).
