This is an amazing sample set of 4 (2 Inch, .47oz) Mini Tins from Crazy Aaron! This set is ideal for party favors, special needs, stocking stuffers, schools and so much more! Glow in the Dark Putty is hypnotic and irresistible! Milky white in daylight, their glow magically appears when the lights dim. You can use our Blacklight Keychain to write messages on the putty and draw special designs. You can even do cool tricks with Glow in the Dark Thinking Putty. After exposure to light (the brighter, the better), these colors will glow for hours. Crazy Aaron worked for years in his basement lab to come up with these mystifying colors. These truly original colors will blow you away and keep you playing for HOURS! And, while room lights are great, sunlight makes these colors really EXPLODE! Electric Colors - gone electric will dazzle you with their iridescent sparkle! These colors stand out in a way that regular putty does not. Now Scented Putty too. This bouncing, stretching phenomenon can be squeezed, kneaded, snapped, stretched, and popped. Putty builds hand and finger strength through a fabulous tactile play experience with unique, unexpected properties and provides relaxing, yet stimulating interaction for children with ADHD, Autism, Fragile-X and other sensory integration issues. Made in the USA. Great for ages 3 and up.
