Great for wallets, grips, wraps, bins, bundles, board games, MacBooks, notepads, notebooks, and much, much more.... We measure our band sizes when squished flat, so a 7.5 inch band is 7.5 inches flat and about 5 inches in diameter. All our bands stretch between 2-3x so a 7.5 inch band will stretch to 21-22 inches or so. It's a bit variable depending on the batch as making bands is a lot like baking. What's included here: 5 7.5 x 0.625 x 0.125 inch bands: diameter is 4.5 inches, stretch is 2-3x or up to 21-22 inches flat Send us a note with the colors you want.

If you don't hear from you, then we'll send a mix based on the colors we have in stock.
