Sold under the brand name "SK-11." This product is from a long-established manufacturer headquartered in Hyogo Prefecture. It's also sold at home centers, but I think the quality and precision of the plating are good. It should be sufficient for a Sunday mechanic. While it appears to have seen little use, there are some scratches from storage. Sockets & Wrenches: Drive size 1/4 (6.35 mm) Sockets: (5.5, 6, 7, 8, 10, 12, 13, 14 mm) Ratchet handle, Extension Thank you.
