Magna-Tiles® Undersea Adventure 58 piece Set

Dive into big-time imagination with the MAGNA-TILES® Undersea Adventure 58-Piece Set, a magnetic building set that transforms any surface into a colorful underwater world. Build domed observation pods, pop open trapdoor tiles, and send diver figures alongside a dolphin, shark, sea turtle, and octopus. With sensory tiles, soft coral, and ocean-inspired details, every build becomes a new deep-sea adventure.

All pieces are compatible with and complementary to all other MAGNA-TILES sets.

MAGNA-TILES pieces are made from food-grade, non-toxic MABS plastic that are free from BPAs, phthalates, and latex. Our magnets are selected with kids in mind, letting them easily pull apart tiles for safe, frustration-free building.

All MAGNA-TILES pieces are built to withstand countless hours of playtime. Our signature lattice prevents cracking, while fastening rivets keep magnets safe and secure.

MAGNA-TILES sets are loved by builders ages 3-99 and designed for kids to enjoy, without instructions or adult assistance. We're advocates for Meaningful Play, that is: Fun and Engaging, Experience Based, Child Led and Developmental.
