For daring marble run constructions, you need a stable foundation. The 120-piece building block set expands the marble run and construction block assortment for little master builders who want to reach for the sky. The white building blocks provide the ideal contrast to the colourful run elements and marbles of the Hubelino marble run and help to quickly and clearly distinguish the construction blocks from the run elements. In this way, the well thought-out colour concept also provides better orientation and structure for the young tinkerers and thinkers – both when constructing and when tidying up. All 120 parts and components of the White Building Blocks are compatible with common components from other manufacturers and can therefore be creatively combined with your existing building blocks and theme worlds. Like all products from Hubelino, the White Building Blocks are manufactured in Germany under the highest quality standards. - 120 building blocks in 6 different sizes - Hubelino bricks can be used with LEGO DUPLO bricks
