查看翻譯opera molto bella, ma, nonostante l'accuratissimo imballaggio, il vetro è arrivato totalmente disintegrato, e ho passato tutta la sera a togliere centinaia di pezzi di vetro😔
查看翻譯Îmi pare nespus de rău ca geamul a fost afectat in timpul transportului. M-am străduit ca ambalarea sa fie cât se poate de bine făcută, ca și in cazul tuturor coletelor pe care le trimit. Sunt convins ca la proximele livrări vom găsi o soluție de compensare ;)
Perfecte genial. Moltes gràcies.
