They seem to work pretty well. I didn't get them for actual injuries though, just cute ones for my three year old that wants a bandaid for every bump. They only stick once so once you lift the tab you will need another.

I bought these Bandages for my son to put in a medical case with a real stethoscope and real thermometers so that he could "be a real doctor" and they are perfect! Since they weren't expensive and there are 100 of them, he can use them whenever he wants and he wont run out for a long time. They stick to the skin, but they're not sticky enough to hurt when they are pulled off, which again, is perfect. I actually usually end up being doctored up while working on college work, so I tend to use these as re-usable book marks and they're easy to take back off the fragile text book pages. I'd imagine that these are pretty great for little cuts too, but I wouldn't expect them to hold up all day if your kid is playing hard and sweating at all. However, there are so many that it would be fine to replace and the crayons are so fun! I only wish they came in green, orange, purple etc. You won't regret these fun band-aids!

These crayon bandages are sooo pretty and colorful too. They come in three colors...red, yellow and blue. And yes, there are 100 of them. The blue ones are rather dark, but that's okay, as they're still a nice novelty bandage. They are somewhat sturdy and a nice length. My box of bandages had the crayon name perfectly centered on them. The box is very cute also. My granddaughters love them, and they're always looking to get boo-boos so they can have one.
