I bought here the sleeve for a Lenovo Yoga Tab 10 ". The envelope is clean processed seams tight and sewn evenly. Unfortunately, the envelope shifts to the tab slightly on the diagonal, not much but enough that it stands out. Probably because the two plates, which are intended to fix the shell probably backwards (otherwise I can not explain their presence) are only collapsed. So, these do not really stop. Nevertheless, I would recommend this envelope repeatedly buy here because it is otherwise ok and really looks great. Perhaps this fall 2 "slip millimeters" to even a pedant like me. Anyway, thanks for the functional and beautifully finished shell.
