Subconscious Cruelty

Gibert Joseph is a legit seller. It's not a wide spread physical store (I think they have only 10 locations in France, mostly in Paris and in Lyon) but they're real, and are quite old and well regarded in France. They're also known to have quite a noticeable part of their stores dedicated to second-hand products.

However, they're mostly physical stores, I don't know how they're behaving online.

I had a look at your link, it says "Occasion" which, in this case, is the French word for "Second hand" (you might want to know that). However, the utmost majority of their second hand products are in very good shape.

Finally, I also read their delivery details and if you're in the US, it's going to be expensive in shipping fees : 20€ (they're talking about 5€ per additional product but it's not clear if the "additional" counts starting with the 1st product or the 2nd one).

5 to 10 days delivery time to the US, not bad.
