did they switch from metal to plastic? all the sets I have are metal, and I bought a set of 10’s at my LYS today, they look the same, but when I opened them, they’re plastic!
They switch to plastic at about 5 or 6mm, I forget which. But all the smaller sizes are the coated metal. Try looking them up under Prym and Aero as well-- it’s the same kind of needle, but they may go up higher with the metals.
