This is a construction ratchet wrench (double-ended). It's a tool commonly called "gacha" and is used by carpenters, civil engineers, and scaffolders. It's a 17mm and 21mm size with the "SUNKEY" logo. It's made of steel with a forward/reverse switching lever. As it has been used, it naturally shows signs of wear. It was regularly cleaned and lubricated, so it operates smoothly every time. Please only consider this if you understand and accept that it is a used and stored item. As it is a long-term stored item, we will not accept returns even if defects occur, so please understand. Please only consider purchasing if you agree. We generally decline "combined purchases" with other metal fittings due to the possibility of exceeding weight limits. (This is to prevent issues like the bottom of the cardboard box breaking.) If it's 2-3 items (that won't exceed the weight limit) other than the maximum of 10 items, we can accommodate it if you allow us some time.
