This is our Grifiti Band Joes Cross Style 12 inch Silicone Band 2 pack. Assorted colors: Black, white, red, blue, green, orange, purple, pink, yellow, and light blue are the options. These are our standard, durable cross bands. They're heat, cold, uv resistant and are made with cooking grade silicone so they are food safe. Great for wallets, grips, wraps, bins, bundles, board games, MacBooks, notepads, notebooks, and much, much more.... These are stretched one direction over an object with both sets of band arms. Then you pull the opposite sides around the object so they form an X cross on the object. The joint is the weak point here, so don't overstretch these by pulling on the joint. We measure our band sizes when squished flat, so a 12 inch band is 12 inches flat and about 9 inches in diameter. All our bands stretch between 2x so a 12 inch band will stretch to 24 inches or so. It's a bit variable depending on the batch as making bands is a lot like baking. What's included here: 2 12 x 0.75 x 0.125 inch cross bands: diameter is about 9 inches, stretch is 2x or up to 24 inches flat Send us a note with the colors you want.
