This is another type of sponge applicator for use with stencils. They come from the US. Like the stencil sponges, they can only be used with water based paint. There are three mushrooms to a pack. They are curved into a nice shape to grip onto. They are ideal for covering large amounts of space to create the single colour block, large stencil pattern look that is so hot right now. They have a smooth texture and give even coverage. We have found them to be easier to use and require less cleanup than stencilling with a foam paint roller.
