Unlike the seal washer, even if it is used for a short period of time it is almost impossible to reuse it once tightened. (Fuel and oil may blur and cause complaints.) If possible, it would be appreciated if there are 50 packs of packs.
Anyway, the price is cheap, a major bike shop in Osaka, with the same level of quality as the one selling roses, can be used without any problems. Since it is 100 pieces, it can be replaced easily with overhaul many more times. If there was any dissatisfaction with precision, I thought that I should go with the oil stone, but I do not seem to worry about that.
