MAC TOOLS USA 3/8 DRIVE 6 POINT METRIC SHALLOW AND DEEP IMPACT SOCKET SETS, PLUS 3 EXTRA SOCKETS. The shallow socket set is the XP6. As you can seein pics it is out of box but UNUSED. The deep set is the XDP6. There are three extra sockets in this set, the 19, 18, and 8. As you can see the deep set has more use, a few have initials, but both ends of the socket are still perfectly usable.
