The goods themselves have a feeling of use especially unlikely and unavoidable rod end. The 8 mm and 10 mm paired left screw type is not the MonotaRO brand but the Osaka soul brand, the manufacturers of the goods received are also different. If you use it separately, rabbits also use horns, left-handed screws with right-handed screw type When pairing with manufacturers saying somewhat disturbing. Although it is an overseas manufacturer item, it can not be felt that the price is less expensive than the domestic manufacturer's item. Considering the possibility that manufacturers change every time, I think that we will avoid purchasing next time.
