The lines on the back are glossy, the surface is dull. The shell is completely opaque. That made me happy, I did not want to semi-transparent.
After a few days in the jeans and other dark pockets I noticed a darkening of the matt surfaces. But had himself transferred to the factory settings with Spühlmittel and Spühlbürste again.
Currently I am considering not to buy a second envelope. This time a Dark. The material is really stable and will not budge. Wobbles just on the long side edges because sometimes nothing. Nice.
