@caterina I had to google it again. The brand is called Zack and the name is Genio. It's about € 10 a piece www.rvsbrands.nl (rvs means in Dutch stainless steel). I don't know if they sell it in other countries. bol.com sells it also. Good luck. I've never seen a better hook. It's self adhesive (and stays!) good looking and very practical.
