Review on FUSTMW Math Gift: Indulging in Delicious Pi Keychain for Math Geeks by Damon Mertz

I ordered the FUSTMW Math Gift keychain as a little graduation gift for a friend who loves math. The message "I ate cake and it was delicious" is cute and fun, and the silver color is a nice finishing touch. However, I was disappointed with the durability of the keychain. After a few days of use, the metal clasp broke off the keychain. It's a shame because my friend really liked the keychain, but it didn't last long. All in all, this is a decent gift idea for a math enthusiast, but look out for the quality.
