ANEX Ratchet Screwdriver, Interchangeable, Gundra, Screw-Fit, 2-Bit Set No.431 I rarely used this as it's small for my hands. I think it's not suitable for people with large hands. The operation is fine. - Brand: Anex - Model: No.31 - Included Bits: 2 types of bits (Phillips, Flathead) This item has been stored for a long time. The silver bit is the original one, but I don't think the black bit is original. Please refer to the images for the condition. Thank you for looking.
