This is our 6 inch Band Joes Cross Style 5 pack of silicone bands. Assorted colors: We make these in 10 colors These are our cross style, durable silicone 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 6 inch band is 6 inches flat and about 4 inches in diameter. All our bands stretch between 2-3x so a 6 inch band will stretch to 18 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 6 inch bands: diameter is 4 inches, stretch is 2-3s or up to 18 inches flat If you're ordering a multiple packs in multiple colors then get the assorted packs and let us know what colors you want. You get a better price in the cart if you order the same thing instead of mixes packs here.
