Duck Brand 1.88 in. x 20 yd. Purple Colored Duct Tape

I'm not sure what everyone else uses this for, but I'm a geocacher here in Arkansas and let me tell you, this stuff is amazing. This camo blends in incredibly well when placed out in the wild. I use it to cover medicine bottles, candy tins, and even plastic containers, and once they're set in place, they are surprisingly hard to spot. It also sticks really well. Geocaches have to survive rain, heat, and everything else nature throws at them, and this tape holds up without peeling like others I've tried. This has become a must-have in my geocaching kit. If you need something that blends in and actually stays put, this is it.
