These tiny little jars contain a little bit of clear colorful putty with glitter. This is perfect to keep in your purse or bag to keep kids busy! My boys love this slime (and so do I) because it is stretchy and builds hand muscles which is perfect for occupational therapy. Each container is 1.5" x 1". These little jars are perfect additions to goodie bags or prize/reward boxes for classrooms or carnivals.
