Review on 6-Pack KIWIHUB UV Blacklight Reactive Tape (6 Colors) - 0.59inch x 16.4ft per Color, Fluorescent Cloth/Neon Gaffer Tape, Super Bright Glow Party Supplies by Shawn Price

As funny as it sounds, I use this thing to mark things like pencils and pens so I can find them when I put them away. Especially my very expensive Wacom pen, which has a bad habit of disappearing from the table. By attaching a small pink flag to it, it will be easier to find. I also use it to label containers (not groceries) to avoid confusion and to label items in boxes. The tape is easy to write on and does not rub off. It's definitely not tape, though, so don't try to hold the car together. It won't last at all. Thanks to the reflective colors, however, details are easy to see in the dark.
