I recommend the large-capacity triangular puff from Daiso.

I used to wash my puffs a lot, but honestly, it became a hassle, so I didn't seem to replace them often. It also felt a bit unsanitary. So, I bought large-capacity triangular puffs from Daiso and apply BB cream or sunscreen by replacing them after a few days. When I applied it with my hands, washing them was a hassle, and it felt like it didn't absorb quickly, but with these, it's easy to apply to hard-to-reach areas like the sides of the nose. Since it has multiple sides, I rotate it to use as needed. There are 60 pieces in the pack, and at 2,000 won, it's super cheap, so it's not a burden at all.
