Full Page Magnifying Sheet

Flat plastic Fresnel lens. This flexible magnifier is 7-1/4" x 10-1/4" and only about a millimeter thick. It is great when you need to scan a list or to look for something in a directory. You can see most of the page without moving the magnifier. Only about 1.5 power, but that can make a huge visual difference. The quality is not high, but neither is the price.

Flexible Magnetics

Need to hold something to a round steel pole? Want to make a magnetic bulletin board? Or to cut some letters for a temporary sign on the side of your car? Relax, the answer is at hand. You need some flexible 12 x 12 rubberized magnetic sheets. The magnetic particles are embedded in a rubber-like material that is easily cut with a pair of scissors. Strong enough to cling firmly to a smooth metal surface or to hold light objects. Sheets are just over 1/32" thick and are self adhesive.

Mag

“Mag” could mean “magic” or it could mean “magnetic.” Some people tell us that the terms are interchangeable in this case. The fleshcolored donut–shaped ankle bandage sticks a circle of (15) 3/8” dia 400–gauss button magnets around your ankle bone. Our each is a set of (2), so if you’re not into magnetotherapy, you still get a slew of cool little magnets.

Magnehesive Tape

The ultimate in refrigerator-door decorating: a 25-foot x 3/4" wide roll of dark brown magnetic tape in a handy dispenser with a tear-off bar. Rip off a strip of tape, stick the sticky side to a photo, art project, or note and the magnetic side will hold it on a refrigerator door, file cabinet, or any other steel surface. Light duty, like all fridge magnets, so stick to notes and pix and other fluff.

Ceramic Power

Ceramic magnets can be quite powerful and have excellent resistance to demagnetization. These rectangular ones are no exception. Add the power of surplus and we'll give you these mighty-mites for bargain prices. This 3-lb-pull guy is 1-7/8" x 7/8" x 3/8" thick, for mounting bigger pix, we figure.

RARE FIND!

Rare earth magnets are usually killers for their size, and these thick nickel neodymium discs are no exception. The price, on the other hand, for (3) 7/16" dia x 1/4" 5-lb lift or (2) 9/16” dia x 3/16” 8-lb lift magnets each stored on a 2" dia steel disc, is a rare exception.

Really Big Retriever

Like a 300-lb Labrador for the shop. Our ceramic lift magnet is mounted in a metal housing with swivel that will attach to a standard threaded broom handle or painter's pole.
