LEGO Duplo

Lego Duplo (trademarked as DUPLO and stylised in the logo as duplo) is a core product range of the construction toy Lego by The Lego Group, designed for children from 1+1⁄2 to 5 years old. Duplo bricks are twice the size of traditional Lego bricks in each of their three dimensions, making them easier to handle and less likely to be swallowed and choked on by younger children. Despite their size, they are still compatible with traditional Lego bricks. Initially launched in 1969, the Duplo range has expanded since then to include sets with figures, animals, cars, houses, and trains. Duplo products are manufactured in Nyíregyháza, Hungary.
