WEAR-RESISTANT AND NON-SLIP：12-point box end doubles the access angles of a 6-point and is offset 15 degrees to create clearance for fingers .Box end opening is designed to grip flat sides of fastener heads, not corners, to prevent round-off.
PORTABLE BAG：The unique advantages of roll packaging make the wrench easy to carry and effectively extend the service life.
PREMIUM MATERIAL ：The wrench is made of durable high-carbon steel. The chrome-plated surface makes the surface of the wrench as smooth as a mirror, improves the corrosion resistance of the surface.
EASY TO USE ：The opening angle is 15 degrees, so the wrench can be flipped to engage the fastener twice in a narrow space, which is more labor-saving and convenient to use.
