I recommend Ohora!

Back when I bought it, they sent a baking lamp for free to new members, but I'm not sure if they still do that.

It is thin and the colors come out pretty, so you just stick it on, cut it with nail clippers, and bake it, and you're done.

It’s incredibly cost-effective considering the time and price, and the pedicure doesn't even fall off easily, so it easily lasts 3 weeks. My toenails just get longer... lol

The staying power is even better if you bake it! I recommend it.
