40 cm around the arm is very small, ... unless you wear it naked.

Why not naked ?
I can proof that, without having Popeye arms, the sleeves are very small.

Thank you to everyone for the input and comments here.
The comments, photos and label posted by rubgum and tiefdruckgebiet confirm my original suspicions that the "rubber" is actually a petroleum derivative like PVC.
Some of the items are attractive to look at and they would turn my head if worn by an appropriate person.
But I can't see me buying one since I would not derive what I seek.

Thank you and Vielen Dank everyone.
