STAMPERS ANONYMOUS-Gamsol Odorless Mineral Spirits Kit. A blending medium for colored pencils! Artist-grade odorless mineral spirits in a convenient sponge-top dabber bottle that results in a pretty almost watercolor look since it essentially melts the pencil lines and erases their grainy appearance. Simply color in a stamped image with colored pencils and apply Gamsol using the blending stumps. Note: this technique is for regular colored pencils not watercolor pencils. This package contains one two ounce bottle of solution two blending stumps and one sandpaper pad. Made in USA.
