It is lightweight, compact and suitable for carrying, I think that making is a very good product. Depending on the purpose of use of the individual, since each tool is compact, I feel that it seems to be somewhat usable in daily work. Also, since the LED light is a type that lights up by tightening the LED part, I attach an insulating sheet attached at the time of purchase and close it tightly and carry it so that the LED part will not be lost. ※ Although it is the description of the feature battery, I was using LR41 x 4 pieces. Please confirm.
