I bought it because I needed an inch socket. In recent cars, bolts and nuts of "inches" are used a lot, and as the number of troubles is increased at business trips, it has been aligned with the set. Although it is not limited to this product, since the product of the socket set is equipped with a holder, it is possible to use it as it is, but the part of the brand at the top (product name etc.) is an obstacle. After purchasing it is easy to pull it off so that it can be easily broken off and it can be easily paid to a tool box etc .... As it takes place at this place, we purchase the holder separately and store it.
