These sponges were specially designed for application of pigments and washing. The soft material makes it easy to work with delicate models without damaging the paint or surface details, removes excess pigment and is very easy to clean. We recommend using this finishing product on a satin or glossy surface. The sponges are available in three different shapes to better suit the varied needs of the fashion designer. You can also cut them into unique shapes with scissors or a hobby knife for a specific application. If you use a sponge to clean your laundry, wait 15-20 minutes for the laundry to dry, then gently run the sponge over the surface to remove excess. Note that the drying time can be accelerated with a hair dryer. Use a few gentle strokes until the desired blending effect is achieved or the effect is completely eliminated. If used with pigments and enamel thinner, allow the thinner to dry for approximately 15 minutes or accelerate drying with a hair dryer before working with the surface. If you are using dry pigments, you can start working with them right away. The product can be removed completely or blended to create smooth transitions using the sponge shape that best suits the surface.
