Allows for angled approaches and excellent operability. [Uses] 9-piece ball point semi-long hex key wrench set for tightening hex bolts and screws. [Features] ・The ball point shape allows insertion into hex sockets at an angle, even in tight spaces or around obstacles. ・Hard chrome plating prevents wear and corrosion. ・Made of special alloy steel for high strength, toughness, and durability. I haven't used it much and have been storing it at home! There are some small, inconspicuous scratches, but I think it's in good condition! Please understand that this is a used item. Thank you very much (*^^*)
