Hey, Big Spender!

How you gonna wrap that dishwasher as a birthday present? Or that barbecue kettle for Christmas? Same way you wrap a moped. In our giant, heavy-duty gift sack. Made of red, cottony-nylonish-nonwoven stuff that's quite tough. Measures 36" x 22" across the bottom and is 48" high, with a white cinch ribbon at the top and a little 4" x 3-1/2" windowed gift-card holder, so they know just who bought them this great big present. Equally useful as a dust cover for a Sousaphone. Extremely presentable!

Drivers In A Disk

The flying saucer meets the screwdriver in these compact driver sets. The larger one is a 2-7/8" dia x 1" thick gray-plastic case with a pocket clip, and holds #3 and #4 flathead, #2 and #3 Phillips, #1 and #2 pozi, and #2 and #3 hex bits, plus a 2-1/4" long driver that fits into a port in the housing for leverage. The smaller one is a 2-piece red-plastic disk, 2" dia x 5/8" thick, with a 1-1/4" chain and a slip ring. It unsnaps to release #3 and #4 flathead and #1 and #2 Phillips bits which fit into a hex port in the housing. At this price, they're perfect for replacement bits, glove compartment, desk drawer, etc. Do handle them carefully, because the cases break easily.
