So, I recently got into lockpicking, I had to pick a single-sided wafer lock on a cash box. With two pieces of wire. And it felt good when I clicked that bastard open

Since I'm new, and want to practice and "feel" it first, I ordered some picks on Ebay.

This set. My question is, I live in Europe, would these picks fit into a European lock or would I have to grind them a bit? Anyone with experience on these picks?
