Its not as popular as America.
I have been pin trading for 12 years now, and frequently visit paris.
There are a good selection and they still have limited editions.
Another thing to look out for is the MEGA traders, they set up opposite Casey Corner (by the ice cream shop) and they are mega MEGA traders. They rarely trade though and have little English, but its amazing to see them all!
