Mirror Tool NMS2-21 Reference Price: ¥7,060 This is a combination wrench I bought about 20 years ago. It has been sitting unused in my toolbox. I am selling it to declutter. Please understand that this is a used item before purchasing. ● The box end opening is designed to prevent stress concentration, making it less likely to damage the edges of bolts and nuts, and allowing for more secure tightening and loosening with its power fit shape. ● The open end head is as narrow as possible, with volume added to the areas where force is applied, making it a new, original KTC head that is an evolution of the traditional design.
