It’s made of hard plastic with leather texture imprint. We have put an old blanket down within the bags floor to help form the shape before packing it. On the improvements:Fingerprint reader could be improved, when the screen is totally off (no fingerprint showing), it sometimes take 2/3 trials before working. The product itself is cheaply made, compared to brands like naturalizer, etc. However the product I got has a navy blue top and bottom. These charges are stronger than I expected them to be. I have boys . 18,4 cm (für Fußlängen von 16,7 bis 17,2 cm)Es ist nicht ganz einfach die Schuhe innen zu vermessen. Great adhesion, easy to use and install, not too thick. I bought this a size larger than my usual clothes size, thinking that would provide enough roominess.
