Using this Aquabeads Mega Refill Set is super easy. First, pick your favorite beads from the 24 - color selection and arrange them on your Aquabeads playset (you'll need to use your own layout tray). Then, use a sprayer (not included) to spray water on the beads. Once you spray, the beads will stick together. After creating your masterpiece, you can store all the beads in the star - shaped palette. When it comes to maintenance, keep the beads in a dry place to prevent them from getting damaged. Also, make sure to keep them out of reach of small children to avoid choking hazards. And always remember, this set is compatible with any Aquabeads playset, so you can mix and match to your heart's content.
