Sofft Tools were specifically developed for use with PanPastels, and can also be used with most water-based art and craft materials to create a variety of exciting new techniques, marks and effects. Finished effects are different to brushes as the brush stroke is eliminated. The semi-absorbent material used in Sofft Art Sponges and Covers is specially formulated for art and craft applications, to hold and release the right amount of material. It is non-abrasive for smooth, uniform results. They can be re-used several times (the number of times depends on the type of color and surface being used), simply wash with soap and warm water, squeeze and air dry.
