Nail buffer I bought with my own money

This is a 1,000-won nail buffer from Daiso. Even though it costs only 1,000 won, it consists of a total of 7 steps, so even those with no dexterity can get shiny, smooth nails just by using them in order. I use it often to trim the tips of my nails after cutting them, and it is also useful when my nails need a shine. But the biggest advantage is that it is very affordable.
