Creative Expressions Sponge Applicator 6 pack. These sponges are the ideal way to remove excess flakes when working with Cosmic Shimmer Aurora Flakes or Indigoblu Gilding Flake. Once you have adhered the flakes to your chosen surface, use the sponge to gently rub away any excess, leaving the applied flake smooth and firmly adhered to your project. The excess flake can then be returned to the container for future use.
