Spare 20mm 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 disc used for binding.
The discs are made of aluminium: 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. And they also allow pages to be folded back fully to save on desk space.
Supplied as loose single discs or as a pack of 24; an A4 notebook uses 11 discs, an A5 8 and A6 5.
