So I got a bunch of these free toothbrushes from a friend, but it is so annoying to try and keep them straight. I have tried to write on them with a sharpie (washed of in a few days), and using little stickers(peeled and got nasty). I bought these cheap rainbow Band-Aids at the dollars store for another reason but realized they could solve my problem!!
They wrapped completely around and are plastic so they won’t get damaged with water. My kids all got their favorite color too! I used them as labels on their water cups too, and wrote their names on them!
I might use them for other things too!
