I think gel nail stickers are convenient.

I hardly ever work on my hands (they usually fall off or peel off in less than a week), but the good thing about pedicure ones is that they last for a month or even two months haha. So I stick them on my feet in the summer. These days, even Daiso has 3,000-won LED lamps, and since I buy cheap gel and a 1,000-won top gel to apply on top, it seems to last even longer lol 😀
