Water beads are a super fun option and so good on your budget. Our tubes hold 25g of beads (enough to fill a big bowl) and are reusable, biodegradable, non-toxic, certified, and loads of fun! We've never met a kid who wasn't totally drawn in on them, they're the ultimate sensory play. Easy to use, hours of fun. Just add water. They come in a convenient tube to restore them once dried out so you can reuse them for another day. Our Beads differ from others on the market as they are very colourful and bright and they contain a retarder, to make sure they don't swell up crazy big and loose their texture, colour or become a choking hazard. Not recommended for children under 4 years of age, always to be used with active supervision by an adult.
