Magnetic Building Blocks 12 PCS

This set contains twelve magnetic cubes made from plastic and sized at 1.65 inches per side. They are designed for toddlers and young children from one to five years old and support sensory play, Montessori activities and early STEM learning. The blocks come in six vibrant rainbow colours and include a booklet with building ideas for animals, vehicles, plants and buildings.

1.65 inch cube size

Each cube measures 1.65 by 1.65 by 1.65 inches, which equals 4.2 centimetres, making them large enough to avoid choking hazards for the youngest users. Magnets are sealed inside the blocks so they cannot fall out during play. Rounded corners and smooth edges give a secure grip and reduce the risk of scratches.

Waterproof durability

The plastic construction is waterproof, allowing the cubes to be used as bath toys without damage. Sealed magnets and durable material mean the blocks maintain their magnetic strength and structural integrity through repeated wet and dry play sessions. They are built to withstand daily handling by children across the full age range.
