Please leave it alone! The product is also withdrawn nciht, unless you pay the Versadnt itself, which costs more than the bag. The material is any plastic that stinks horribly! The zipper is sharp and pulls the finger at. Unfortunately, the absolute bad buy. Positive recessions are either faked or the people who get good merchandise. For me that was not the case. The bag must be entworgt - presumably special or nuclear waste ....
