A small drawback is that the volume buttons are not available in closed envelope, so that I can personally but live. The material Kund has a roughened texture and pleasant to the touch. The inside is soft and functional, reminiscent of the optics, but a bit of a cardboard box that does not look as nice.
When unpacking I could perceive no unpleasant chemical smell, like I've seen at much higher-priced products which could hang out first two days for airing. The magnetic closure is blue and delicate and a little weak, I've already beautiful and elegant seen from other companies, then mentioned products cost but also like to have 3 times as much.
My conclusion: For me, the envelope is perfectly fine for the price / performance ratio of my expectations were met. Who a noble designer object is expected disappointed and should engage much deeper into their pockets, for all who can do without such frills, I can recommend the sleeve.
