Water Beads, Water Balls, Decorative Water Beads for Plants, Decorative Gel Balls for Vase Fillers (Multicolor, 20,000)

There okay , not great. They do grow within 24hrs but only to around 1cm diameter Not sure there's 20,000 (haven't counted) Item comes in a sealed plastic bag no tub or box

Those are so much fun and keep my daughter busy for ages! Much better and not as fragile as the original Orbeez and better price. They are teeny tiny plastic balls when they arrive and grow in the water
