Tunewear today announced a new high-density transparent silicone case, the case for the iPod shuffle. It users the same silicone found in diving masks which allows for both scratch protection and a clear view of the iPod's original form. The company says that any ink or pen marks can be removed with the swipe of a hand and that the case can be washed (using soap and water). The ICEWEAR shuffle enables access to all ports, features shock absorbing ribs on each sides, and includes two cap covers--one for the regular USB cap and the other for the USB cap with the lanyard--as well as a removable ball-bearing style chain to prevent users from misplacing the USB cap or lanyard. It will ship at the end of May for $20.
