Set of two yellow speed wrenches, 300mm and 350mm, made by SANKI, a manufacturer that went out of business 20 years ago. They were well-regarded tools, but are now rare and retro. These wrenches can be adjusted to various shapes with a single touch, and their strong grip allows for the removal of damaged nuts and bolts, improving work efficiency in the inspection and repair of factory machinery. I bought several of these, and I'm offering unused ones. They were originally over 10,000 yen. - Model: Speed Wrench - Color: Yellow - Size: 300mm, 350mm - Quantity: Set of 2 - Features: Strong Grip Thank you for looking.
