Yes. I use them myself sometimes if I've got a cut on my fingers that I don't want to get dirt or other gross things in while gardening or changing nappies. They're sometimes useful for the kids too, though they prefer brightly coloured ones with cartoon characters on them.
I can't live without them.
They are a staple, because leaving open cuts is Not one of my favourite things to do!
They are a must for any house I believe.I do a lot of gardening...so I need them all the time.
Every winter I get painful deep skin splits right at the fingernail, so need band aids but I've noticed recently that every type I've bought is either the Goldilocks effect - too big/wide, too small/narrow, etc, and the latter one doesn't stick very well on the tip of the finger before it starts peeling off.
I play violin so have to have my fingernails short which contributes to these splits. I also work outside, doing a junk mail round and occasionally a letterbox will win the war between it and my finger.....
