InvisibleSHIELD Full Body Protector - Sony Ericsson K850

I don't know how it can be described as "perfect fit", but it does the job. Ot covers the screen, from the soft keys up to the speaker, and the back, as well as the top and sides. The material is pretty decent, but almost identical to the stuff Displex use. The applicator spray helps to position the panels - don't use too much or it wont stick properly. However the panels are NOT accurate. also you have to make sure they are exactly positioned or you will find edges that don't stick to the phone, but really attract dust. There will be air bubbles, that never come out, but as long as you're careful, it should be minor. I don't think you can remove and replace it once it's dry - and you do have to give it 24hrs to dry. i still use a pouch to carry it in, but it does look extra shiny now that the sides are no longer a matt finish on my k850i.

brilliant product fits perfectly
