Blockaroo Magnetic Foam Builders - Trunk Set

The Trunk Set is designed for children from age 3. At 3, children start building with intention and making up stories around their creations. The open-ended format keeps it genuinely interesting well into the primary school years — a 6-year-old with 50 pieces and an imagination has a lot of building to do.

Yes. The blocks are made from soft, non-toxic foam with no sharp edges — safe even for children who still mouth toys. The internal magnets are fully encased in foam and not accessible. Blockaroo blocks are safety tested to exceed international toy standards.

Absolutely — that's one of the best things about a 50-piece set. There are enough blocks for two children to build their own structures simultaneously, or to work together on a single large build. The blocks are designed to encourage collaborative play, and children naturally start negotiating, sharing, and planning together.

Yes — the foam blocks float in water and cling magnetically to the metal liner inside most standard bathtubs. Children can build on the side of the tub, float pieces across the surface, and generally turn bath time into building time. The blocks are fully waterproof and mold-free — leaving them wet causes no damage.

Top rack of the dishwasher. The blocks come out clean and completely undamaged by the wash cycle. For a quick rinse between sessions, a tap works fine too.

The trunk holds all 50 pieces securely with a lid. It makes cleanup a single step — children can collect the blocks and place them in the trunk themselves, which is a great independence habit to build. The trunk is also compact enough to take to a friend's house, on holiday, or to a classroom.

Yes — every Blockaroo set is 100% compatible with every other. The Trunk Set can be combined with the Robot, Airplane, Critter, Castle, or the 100-piece set for even larger builds. It's a great reason to keep expanding the collection one set at a time.

Mostly: a lot of building, rebuilding, and playing. Block play is one of the most research-backed activities in early childhood development — children develop spatial awareness, shape and colour recognition, fine motor control, and early maths thinking through the simple act of figuring out how pieces fit together. The independence and confidence that come from building something on their own are harder to measure, but just as real.
