Here's a great security stocking stuffer for under $10.

The ExcelMark is an inked roller stamp for those who don't have, or don't want to buy a shredder, but still need to get rid of sensitive papers. This device has a special pattern on a convenient rolling design which quickly hides addresses, social security numbers, account numbers, ID numbers, etc. And it can do a few things a shredder can't do, like cover private info on prescription bottle labels. The 1.5” wide roller holds the ink inside, so there's no need for a separate, often messy ink pad. I've used it several times and found that the ink quickly dries as you roll it. It works well on all regular paper, envelopes and package addresses. The company says the ink inside has a total length of stamp coverage that can reach 100 meters, which is about 328 feet. Not to worry, because the ink can be refilled when it runs out. The Excel Mark alone doesn't seem to be available alone, but is being sold with 3 ink refills for $12.99. I think this is a good deal. I wish it was available when I bought mine. If you only want the stamper go to the bottom of the page at the link below. You'll the exact same device under a different brand name for under $9.  (Remember that Amazon prices can change at any moment.) 

ZipSnip won't let those pesky thick plastic clam-shell packages drive you crazy trying to open them!

When scissors can't cut it, these can. The multi-purpose 4V cordless ZipSnip cuts cardboard, rubber, plastic and more. I tried it on a clamshell package and it works great, keeping hands and fingers out of harm’s way. The blade operates at 260 rpm (no load) and its maximum cutting thickness is ¼ in. The ergonomically designed cutter is constructed of high-impact nylon resin with a comfortable mold grip. The tool’s trigger is an integrated part of the handle with a top-mounted lock-out switch for added safety. The cutter has a built-in charging port that brings the tool to a full charge in five hours. An LED indicator on the tool’s body lights when the battery is fully charged. The lithium-ion battery can maintain a charge for several months. MSRP: $34.99.
