X Block is an innovative building block concept that supports children’s fantasy-evoking games, creativity and motor skills. The building blocks made of impact-resistant plastic are manufactured in Denmark and were specially developed as playing options for childcare centres, schools, and so forth. Thanks to the special cross-shaped feature on the sides, the bricks are easy to assemble; when stacked in a brickwork pattern, stable constructions are built. The blocks are very robust, with a durability of up to 20 years.
