When I tried to unwrap the mat, I've got a bad feeling when I saw the packaging film, she was in fact already "merged" to part with the mat. Reason, the plasticizer in the exercise mat. When removing this film thus tore some places the surface of the mat by pressing. It looks so pretty battered from without to have been in use. The stand these plasticizers also health into disrepute, this mat can not appear in a better light.
