Dear Victorie, Although I read French, I can't write it well enough for a reply in French. So, in English: In the USA, it is pretty easy to find these black trim pieces. I am pretty sure these tiles came from American Olean company. However, I think you could find them online with Wayfair. but that is here in the USA. Ann Sacks has similar. There is a Spanish company, ADEX, that I have also used. They have a "studio collection" that might have black trim pieces. Good luck! Best, Kathryn Long, ASID
