This is a KTC 1/2 inch ratchet handle. It's 250mm in size. I think I bought it for around 4000 yen. I bought it by mistake, thinking it was 3/8 inch, so it's almost unused. I'll include a 1/2 inch short extension and a 1/2 inch 12mm socket for free. Both are also almost unused. I am selling these because I am quitting my job as an auto mechanic.
