Illuminated magnifier for $2.51 (including shipping)

For the last few months I've been learning kanji at Wanikani (my wife is an editor at the sister site, Tofugu). Today, I found a few Japanese coins in a drawer, and I wanted to see if I could read the kanji characters on them, but they were too small for my ever-worsening eyesight. I pulled out my trusty illuminated magnifier that I bought on Amazon for $2.51 (including shipping) and used it to easily see the characters. It uses 2 AAA (I don't remember if they were included).
