Genuine Snap-On sockets, all matching and complete with the Snap-On rail. This is the Flank Drive Xtra (FDX) set, not standard flank drive. Used but in good working condition. They’ve been used for normal work so there are marks and grime, but nothing cracked, split or damaged. All sockets fit the rail properly and are clearly marked. Sizes run 6mm up to 20mm (full 15pc set). Some cracks on the rail itself but that’s it. Great set and never had any issues with it.
