It's the Missha Waterdrop Sponge.

The price is cheap.

Since puffy sponges are hard to use for a long time, I think it's better to replace inexpensive products frequently.

When I apply foundation with my fingers, it definitely gets on my hands and doesn't feel like it applies evenly, but when I use this sponge, it applies moistly and evenly haha.

I recommend this set, including the sponge stand I bought from Daiso haha. It feels a bit unsanitary to just leave it on the floor, so this is really great. It's cute too.
