TPU stands for thermoplastic polyurethane.  The material is like a hybrid of plastic AND silicone. This TPU material will give you the solid protection of a hard case and grip of a silicone skin.Advantages of thermoplastic polyurethane: Light weight, most durable, corrosion resistant, shock absorbent, dent resistant, will not cut/tear/scratch.  It is flexible but will always return to it's original shape.WHY IS THIS BETTER THAN A SILICONE SKIN?(1) The traditional rubber/silicone skins are hard to get out of your pocket.  Whereas, this material will slide out of your pocket with ease and you still get the soft "grippy" feel in your hand.(2) Silicone skins are flimsy.  TPU material will retain it's shape and fits like a glove.(3) Silicone skins will accumulate lint and dust.  TPU material will repel lint/dust.WHY IS THIS BETTER THAN A HARD CASE?Hard cases can be difficult to remove when you need to access your battery or memory card.  This skin can be easily removed so you can access back door quickly.Suitable only for theHTC Incredible 2 6350cell phone.This isNOTfor the original HTC Incredible 6300 or any other model.
