The sponge has worked good so far at blending my makeup. It’s pretty soft, especially after dampening it. The only complaints are that my foundation left stains on the sponge even though I have washed it, and pink coloring was washing of the sponge after washing it the first time which was a little concerning.

Great for liquid foundation

These are great quality and value! I saw them on a TikTok and thought the price made them worth trying. They apply product well and evenly and they last a decent amount of time as well.
