Here's not much to add. The envelopes are of good quality. The tape sticks (I myself stick right now in winter but still an extra on it) .In fit an envelope up to two DVD cases similar properties (two games, currently Porto 2.40). Had no problems with this product. Of the approximately fifty buyers that I have supplied with this Luftpolstertaschen, there was no complaint about broken previous goods. Point to: Super product. Oh, almost forgot. For those who only occasionally need that, I would recommend to take the offered here 50 pieces. I myself have ordered 100 and got to one and a half days a box of approximately 60x30x20cm delivered to your door. Only times that do not have much space for people. MfG
