4 years & up. From fine grit to coarse, stringy to slippery and different textures in between, children will experience finger paint in a whole new way. Just mix a small amount of the food grade additive to finger paint and paint away. The unused portions can be stored in an airtight container. Great for sensory exploration and the visually impaired. The food grade additives are not likely to cause allergic reaction. If you have a student who is allergic to starch, corn or rice, avoid using these additives. Fingerpaint sold separately.
