Unfortunately none of the AA vendors are in Europe. Only USA and Canada
Me and @Imogena are both in EU. I´m not sure where OP is located but If I was in the US or Canada I would also only buy from AA vendors.
I have never purchased anything from Amazon for my birds.
I'd check out sites like Etsy. There are a few vendors here that started their shops on etsy, and there are vendors from all over the world making different things. It's also super easy to contact the shop owners to ask questions, in case you're unsure of metals, etc.
Other than that, look at the manufacturers of toys that local pet stores carry, or even check the websites for exotic/bird shops around the EU. Typically bird stores will carry more variety, and give you ideas on what toy makers you can trust.
