Please note this is not Silicone

I ordered this pocket and I did return. It is made of polyurethane, which is very different. Certainly it is practical, durable, washable. But it is far from having the flexibility and ease of handling of a silicone pouch.
I had already purchased the same pocket in a specialty store AIX EN PCE, sold for silicone. The trader has taken me claiming to have been deceived by the representative of the house DE BUYER who has not warned of the material used (polyurethane). If for some, it does not make a big difference, savvy confectioners will realize this, and anyway it is a misrepresentation of the quality can be unintentional on the part of AMAZON, but which should make the change.
Otherwise, I have always been pleased by the AMAZON services.
