Excellente marchandise. Mais les frais d’envoi c’est à revoir car j’ai deux commandes qui arrivent en même temps et je dois payer deux fois les frais au lieu d’un. C’est vraiment absurde…

C’est un beau travail. Très belle pierre. Mais il faut revoir votre politique d’envoi car c’est vraiment pas très écologique et correct…
