What size dealer button did you get? I had three round DBs made - each one 63mm - which is larger than the 60mm ceramics made by BR Pro Poker. And some people play with 49mm buttons.
I thought the quality was just fine. Laser engraving is flawless. The only negative about them is they are light weight. If they had the same weight as ceramics, I wouldn't have anything negative to say about them. I mean, they are pricey, but they are coming from France, after all. It's not like
Amazon has them with 2-day free prime shipping.
As for the cut card, yes, it's thicker than normal, but this was also explained to me prior to me placing my order. I prefer the thicker cut card tbh.
