I recommend the versatile puff.

It is none other than the Espoir puffʕ-᷅ᴥ-᷄ʔ
I tend to stock up because it's cheapest during the Tmon 10-Minute Attack or Olive Young sales.

Do you ever feel that the puff usually included with cushions isn't a good match for you?
It is the most reliable puff to use in those situations, so I always keep it stocked! Especially with the Banila Co White Cushion

It fits perfectly, so I'm really enjoying using it.

Washing puffs too often is a hassle, so I usually rotate between two. However, sometimes it's just easier to swap them out. Since they come in one bag, I think it's good for hygiene.
