This assorted multi-pack of "Build It" activity kits is published by Silver Dolphin Books, an imprint of Printers Row Publishing Group. Each kit in the series combines an illustrated educational guidebook with a set of interlocking slotted pieces that children can assemble into a three-dimensional model — no scissors or glue required.

The "Build the" series covers a range of engaging subjects including dinosaurs (Build the T. Rex), space (Build the Solar System), robotics, and more. Each kit includes a full-color book packed with facts and illustrations alongside all the pre-cut, pre-scored pieces needed to construct a detailed 3D model. Designed for children ages 8 and up, the kits encourage hands-on learning through building.

The pack sold at Costco contains an assortment of titles from the series, offering variety at a value price point of $12.99.
