Take your Sonic Tools with you. This Sonic MCS 94-piece set includes 1/4" and 1/2" drive ratchets and sockets in an easy to carry case. Inside the case are two laser-cut foam trays just like Sonic toolboxes. Each tool has a perfect place in the foam along with the corresponding label. Also included are extensions, socket-driver handle, and bits. Sonic ratchets and sockets are made from Chrome-Vanadium steel for durability and resistance to rust and corrosion.
