This is an assortment of various sized rubber transmission belts for whatever purposes you can think of, these are the same type of belt used in cassette decks and things (remember those, walking down the street with your boombox on your shoulder breaking it to some beats... or something like that, daddy-o, yeah I'm super groovy cool like the kids...).
Each pack has somewhere around 30 belts in it, fairly random assortment, with circumferences (total length arond the ring, not diameter) somewhere between 10cm to 25cm without stretching. But no guarantee as to exact sizes in each pack, it’s just an assortment of common belt sizes. These are “square profile” belts, not flat, not round. The thickness is about 1mm to 1.5mm. Less stretchy, stronger, and less... grabby... than normal rubber bands.
Nothing wrong with good old belt and pulley drive mechanisms for your little creations, easier than making gears.
All of our products are shipped from Christchurch, New Zealand using CourierPost for NZ, and Airmail for international.
