NGK Benri Latch BS-3 I believe this is an older model, as I used it quite a while ago. It's a socket wrench, and on one side, the metal fitting that keeps the sliding part from coming off is missing. However, the socket doesn't come off even when slid. The sliding action also feels a bit stiff. It should still work fine as is, but it might be better to secure it if possible. Sizes: 17, 22, 19, 24 Please refrain from purchasing if you are overly concerned about the condition, as this is a used item.
