This bandage is made of a relatively thick plastic material. She holds and sits well. The thumb loop was not a problem for me, my thumb is not cut off. One must however be aware that they are really only lightweight support and is therefore not suitable for immobilization, but only to support.
The material smells very unpleasant and had first airing a few days.
It, even if it would be a little longer for the wider Mr. wrist bandage this would be nice.
