When using as makeup, the best application tools are your finger, or a flat brush. We like using our Angled Eyeliner Brush.
For large area application, a regular wedge makeup sponge works great.
To remove Glitter Cremes, the fastest method seems to be just wiping with a paper towel. The product base is waxy, like a lip balm, so it comes off well with a good wipe. Any remaining residue can be washed off with soap and water or your regular makeup remover.
This is not a water-proof, smudgeproof type of makeup, but it does hold up well for most applications.
