Platzwunder of peculiar material

The material is apparently not the best, because it smelled bad after plastic.
The supplied elastic band I've thrown away immediately. So verrotzt looked like I did not buckle my my good flash. But it can be fixed with a Velcro strap to the camera.
A manual is not available, but the structure is self-explanatory. The diffuser fits only to an external flash, the internal flash of the camera this is not suitable.
It can also be easily re-assemble and then has a handy format and can be neatly stored.
