I wanted to have a neoprene sleeve for Kindle HDX 7, which protects the Kindle including origami envelope during transport. I already had one that is read sogerade times use it, but it was sitting so close that I had to be very careful when closing the zipper. This has sufficient air, without the instrument is too loose. At the processing there is nothing to complain right away first. The device can be charged located in the envelope. It was noted no odor.
