The Zest-it Blending Sponge is a fine sponge, impregnated with Pencil Blend, in a pot with a screw top lid.
It was developed for a company that specialise in Parchment Craft products, as a controlled way of using Zest-it Pencil Blend to blend Coloured Pencils and Oil Pastels.
The sponge holds 15 ml of Zest-it Pencil Blend.
When you press your brush, paper stump or tortillion onto the surface it soaks up Zest-it liquid.
The amount of pressure and the length of time on the sponge gives you more control over the amount you use.
