Piece sponges that capture both cost-effectiveness and hygiene

I recommend these makeup sponge pieces. I bought them at Olive Young, but Daiso sells similar ones. There are 18 in the pack, and they are on the smaller side. Sponges get dirty after just a few days of use, and washing them is a bit of a hassle, so I think it's best to just replace them frequently with cost-effective ones. The texture is nice and dense, so makeup applies well.
