Kleancolor Blending Sponge grows to about twice its size when wet, and absorbs minimal product so your favorite formula lands on your complexion—not your sponge. When wet, the super-soft material provides an even, smooth blend and bounce. The large, rounded surface area ensures a quick application while the contoured tip offers precision. Beautyblender has chosen to use non-toxic, water-soluble dyes. For this reason, your beauty blender may shed dye for the first couple of washes—similar to a pair of blue jeans. Once you squeeze the water out of the beauty blender, the excess dye is removed as well. The dye does not transfer to the skin.
