Honestly, it's a bit difficult to get enthusiastic about sponges, but these ones from Missha aren't a bad option. All four colors are about an inch to an inch and a half long, so you can certainly use them easily. The sheer number of them is part of where the appeal comes in: you can actually use a sponge for two weeks and throw it away, which is sanitary, rather than having to reuse a sponge or clean it, admitting that the latter option is by far the most ecologically friendly.
