Comfun 22000pcs Mini Styrofoam Foam Balls DIY Craft Supplies for Stick to Slime and Wedding Party Decoration,0.1 to 0.13 Inch Mixed Colors

The product info doesn't give a good idea of the size of this product. Each bag is only about 7' by 7.5 " by 1/4". Seems over priced. The bag material is stiff and one had a small tear in it that the balls were coning thru, so if you aren't going to use it right away you'll want to put it inside another bag.
