Fastrax 7-Piece Changable Driver Set

One handle, now seven wrenches! This space saving tool is ideal for
those not wishing to cart the tool box around. The hollow aluminium
handle houses 1.5mm, 2mm, 2.5mm and 3mm hex wrench bits, along with two
Phillips sizes and a slotted bit. Simply select the one you want and
slide into the handle end where a pre-installed magnet keeps the bit
securely in place.
