Take your Sonic Tools with you. This Sonic MCS 99-piece set includes 1/4", 3/8", and 1/2" drive ratchets and sockets in an easy to carry case. Loaded under the top is a full set of Sonic combo wrenches from 6mm to 22mm. Inside the case are two laser-cut foam trays just like the Sonic toolboxes. Each tool has a perfect place in the foam along with the corresponding label. Also included are extensions, and bits. Sonic ratchets, socket, and wrenches are made from Chrome-Vanadium steel for durability and resistance to rust and corrosion.
