The material feels good, more like rubber, but still relatively smooth and not too adherent.
The sheath extends beyond the edge surface of the display and provides together with a sheet so a continuous protection.
The border of the envelope is performed in another (more plastic-like and shiny) material; at the transition (especially at the recesses), there are a few (very small) protruding "nose" to visually recognize only upon closer inspection, however, you feel it when attacking. However, they are so small that they are hardly even abbekommt with a pair of nail scissors.
The surface is as it seems also relatively susceptible to fingerprints and especially signs of wear (model "black"), which may perhaps be the biggest shortcoming - let's see what it looks like after a long time.
In total, however, a great protective sleeve, she would buy again - and not only in the absence of other present alternatives ;-)
