The FlexiShell Dot for iPod touch 4G is a soft, translucent TPU shell that lets you show off a limitless array of colorful dots - in any pattern or arrangement you"d like!Here"s how it works: The translucent TPU shell is designed with circular dimples on the inside of the case - in the shape of traditional polka dots. Included is a bag full of colorful dots that you can pop in place inside the dimples, in any arrangement you like. The best part is, these dots can be removed and rearranged as many times as you like - so you can change the look of your case as often as you want. The colored dots are visible from the outside of the case, without poking through or falling out, so the back of the case remains smooth to the touch.Prefer a more muted look? No problem - the FlexiShell Dot looks great even without any colored dots in it. A fun case and fun colors for a fun device.
