Hey everyone. I recently bought the black Incipio feather case for my iPad Mini to be used in conjunction with a sleeve, and the case itself seems great except for one thing: The texture, while matte, feels rather grainy/bumpy on both the outside and the inside of the case. It's hard to describe... It feels sort of like it's covered in bits of dust, but of course it isn't. The texture is not visible. Is this how they're supposed to feel? I was expecting it to be totally smooth. If anyone else has this case, does yours feel totally smooth or are there grainy patches? Thanks for any input.
