حلوة بس بتفرول بسرعه جداااا

Added to a bedroom wall along with insulation and reduced noise by 60 percent. Did not use adhesive.

Bien immerger les mousses dans l’eau et bien laisser sécher avant de les fixer. De cette manière ils reprennent leurs formes initiale. Produit correct sans ce ruiner

This product is awsome i brought two sets in total but about 4 weeks apart, I was so happy with my first order I had no problem in ordering again. The product does come very flat and compact but I found I just left each tile for 24hrs and most had popped up to full size the ones that didn't I just filled the sink with warm/hot water and soaked them and they soon popped out to full size. I would of given 5 stars but a couple tiles were abit rough around the edges so not 5 start perfect but if I could of given 4 and half stars I would of. You won't regret buying these great product!!

Ca reste des mousses très légères et qui n'absorbent pas le son comme du matériel pro, elles finissent par s'effriter au bout de quelques années ça dépanne ceci dit !
