I used multiple methods of removing bolts, magnets, paper, magnet inserts. Nothing like this. Industrial finish so the look and feel tough and high quality. Because of these sockets Im going to buy more Koken tools.

Really grips the bolts & nuts with the spring-ball". Wish this "style" was available in a more easier-to-come-by store. (took quite a while to find them in their online catalog, which could use a major overhaul to make it easier to bbuy, which translates into more sales)
