Purple and Pink Mood Mudd Changes color with the heat from your hand just like mood rings! For adults and kids over age 5. Here's some squishy fun when you're in a manipulating mood at the office. Mood Mudd, which is made in the USA, is soft, stretchy, stringy and a bit sticky, with a feel something like a cross between dough and jello. Mood Mudd comes in a 3" diameter x 1.75" tall resealable container, 4 oz. each. Does not stain and is nontoxic and water soluble. Made in the USA.
