KTC Socket 11/16, Drive Size 12.7, Overall Length 100mm. Astro Products Combination Wrenches 1/2 and 7/16, a set of 3. The socket is unused, and the combination wrenches have been used a few times. I used these for maintaining a classic Mini, but I no longer need them, so I'm selling them. If you have any questions, please ask through the question function.
