So, I purchased these to put in my locker at work, and as soon as I opened my locker, I was assaulted by my colleagues all wanting a mustache magnet! These little magnets are SUPER strong! They hold up papers and pictures in my locker! Amazing! They are so whimsical and fun to have around. I highly recommend these as gifts for your co-workers or anyone else for that matter! Thanks Birchbox!
