I recommend a cost-effective cushion puff.

I recommend the Daiso cushion puff. Even when I used expensive ones, they would wear out quickly and the straps would break, rendering them unusable. The ones sold at Daiso are cheap at 1,000 won each, and they apply well to the face. I don't really notice much difference compared to using a puff from a cosmetics brand, haha. Washing puffs is a hassle, and they don't clean well and tend to tear, so I just use them for a while and then replace them. Since they are cheap, it's less of a burden, haha... If you want to use something cost-effective, I recommend this one!
