I bought a few months ago this Handyhü'lle. It fits really well on the phone and is an optimal protection. My phone is white, so I wanted to have the transparent Hü'lle. But after some time began the envelope to verfä'rben yellowish se. I suppose, by the heat generated during the phone ?! It was getting darker, so I've done again. It did not look nice. I tried to bleach the Hü'lle with Danclor, or Verfä'rbung rauszubekommen - without success! I wÃürde they no longer buy because of Verfä'rbung but wä'hlen a fä'rbige HÃülle that is not transparent!
