The rubber bands are #64 size latex rubber bands.
I bought a large bag from Office Depot and have hardly put a dent in it. Should last for a few more seasons. Keep them cool and in the dark to help prevent dry rotting.

Tip always check the AGE of the rubber bands you are buying. Nice light tan color and no cracking when stretched, Keep 'em out of the sun!
