Martha Stewart Crafts Erasable Liquid Chalk is more durable and long-lasting than regular chalk. Applied like paint, it doesn’t smudge and washes away with a damp sponge, leaving no shadow. A convenient foam pouncer makes stenciling and silkscreening quick and easy. For best results, use it on top of Chalkboard Paint that has been conditioned. Water-based and non-toxic.
Note: each bottle does have an interior seal under the foam cap that must be removed before first use.
