Sofft Tools feature non-abrasive micro-pore sponge surfaces, designed for artists and crafters to hold and release the right amount of color for smooth results. Developed for use with PanPastel Colors, these tools can also be used with most water-based art and craft materials for a variety of unique marks and effects. They are reusable and come in different forms and shapes to fit artists needs. The different shapes allow for precise marks, blending, layering and more.
