We call these Band Joes Rounders. An architect friend ask us to make these for him. They easily roll on and off his rolled up architectural plans. These are great for artwork, surverys, plans, and much, much more... They have a round cross section similar to hair bands. 2.25 inches flat x 1/8 inch round cross section. They are 2.25 inches flat; 4.5 inches in circumference, 1.3 inch diameter and they have a round cross section. Perfect for use as hair bands, on boxes, cards, and shafts. These are made with our durable, long lasting, cooking grade silicone. They are UV, heat (to 600 degrees F), cold, and chemically resistant bands. They will not fall apart like desiccated traditional rubber bands so you'll can get years of use. Perfect for wrapping up just about anything small or using as an o-ring or gasket. These are made with long lasting silicone instead of rubber. 

We measure our bands flat. So, when pressed against the desktop, these are 2.25 inch flat. These barely stretch to 2X.
