28mm coloured plastic binding discs for Atoma disc-bound notebooks. Allows you to create a notebook of almost any size, or change the thickness of an existing notebook by changing the diameter used for binding.
The discs are made of plastic: strong enough to withstand the rigours of daily use and overly-vigorous paper-peeling, yet light enough not to add unnecessary weight to the pad, and not so big that they get in the way when you write. They also allow pages to be folded back fully to save on desk space.
16mm discs are the default size for new Atoma notebooks; larger 20 and 24mm discs are available.
Supplied as loose single discs in random colours, or as a pack of 24 assorted colours. An A4 notebook uses 11 discs, an A5 8 and A6 5.
