Messy Play Kits

What's in the box: Each kit holds the materials for one themed messy play activity, such as oobleck, color changing slime, fizzing play or a dinosaur dig.

Messy Play Kits is a small US shop selling sensory and science activity kits for young children, started by a founder with a background in early childhood education. If you want a recurring box, note that the site now plainly states there are no subscriptions. Everything is sold as individual kits, and the business is ending its physical product line at the end of 2026. Remaining stock is sold while supplies last, and items will not be restocked once they sell out. The lineup sticks to classic messy play: oobleck, color changing slime in galaxy, unicorn and mermaid themes, a fizzing snowman, playdough soap, a handprint keepsake kit, and a larger Dinosaur Dig kit. Most single kits are priced between $12.95 and $13.95, and the Dinosaur Dig is $49.95. The shop also offers sensory bins and seasonal fall and Halloween activities. These are simple, hands on activities rather than a structured science curriculum, which suits preschool and early elementary kids who learn by squishing, mixing and pouring. The brand plans to continue with parties, events and library programs, but that does not help shoppers who want something shipped to their door. It works well as a gift or a one time stock up before the shop closes. It is no longer an option as a subscription.
