Mattoncini

Mattoncini is the Italian term for small interlocking plastic bricks used as a construction toy. The expression is commonly associated with LEGO, the best-known brand, but it also applies to many compatible bricks produced by other manufacturers. The bricks typically consist of hollow units with studs on top that connect with tubes inside other bricks, allowing seamless, modular building.

Design and compatibility. The interlocking system is designed to enable bricks from different lines to fit together, provided they follow the standard stud-and-tit system. Bricks come in a wide range of shapes and sizes, including standard bricks, plates, slopes, hinges, wheels, and specialized elements. A 2x4 brick is often regarded as a basic unit. Most bricks are made from ABS plastic, chosen for durability, colorfastness, and resistance to wear. The system supports extensions such as sets for architectural models, vehicles, and themed play themes.

History and use. The concept originated with LEGO in Denmark, which began marketing the interlocking brick system in the mid-20th century. Since then, mattoncini have grown into a global hobby and educational tool. They are used by children for free-form construction, by educators for STEM learning, and by adults for creative sculpture and stop-motion animation. The term mattoncini is used broadly in Italian to refer to LEGO-compatible bricks, regardless of brand.

Brand landscape and variants. In addition to LEGO, numerous brands produce compatible bricks, including larger-brick lines for younger children (such as Duplo) and other manufacturers offering alternative colors, shapes, and packaging. The ecosystem emphasizes compatibility within the system, while branding often highlights unique features or themes.

Safety and environment. Toys labeled as mattoncini are subject to safety regulations in many regions, including choking-hazard warnings for small parts and compliance with standards such as EN 71 in Europe. Concerns about plastic waste have driven ongoing discussions about sustainability and recyclability in the toy industry.
