Recommended age: 3+

Always supervise young children during play, inspect the product before each use, and discontinue use if any piece becomes damaged. The included 1" acrylic cubes are not suitable for children under 3.


Wood: Each piece celebrates the natural grain and texture of real wood. Because we avoid heavy lacquers and plastic coatings, the surface may feel slightly textured or “raw” compared to mass-produced toys. This is intentional—and part of the charm and character of working with real, natural materials.

Acrylic: Not all acrylic is created equal. At Maison Rue, we use high-quality, crystal-clear acrylic specifically made for children’s play. Our Acrylic is CPC + CE certified and safety tested to meet and pass all CPSIA & EN71 standards, including testing for lead and phthalates.

Please Note: Acrylic is a premium, durable material, but unlike glass it is naturally softer and may display light surface marks, scratches, or subtle cosmetic variations from manufacturing, hand assembly, packaging, transit and over time through normal play. These are normal characteristics of the material and production process and are not considered defects. They do not affect the safety, durability, or play value of the product.

Care: Wipe clean with a damp cloth and dry immediately. Do not immerse in water or use abrasive cleaners.
