I've used them before but just for my big toes... I had surgery on my toenails (ingrowns from dancing...gross, I know) and now they're a lot narrower than they used to be. I only used them for special occasions when I'd be wearing open-toed shoes (a party, a wedding, winter formal) just so I'd feel more confident. I'm still self-concious about my toes but I don't use fake nails anymore. It was too much of a hassle. I do think it's weird when people use them on all their toenails. That's just odd.
