Theo Blocks

Meet The Theo Blocks: bold, beautifully clear large square acrylic blocks designed for open-ended play that grows with your child.

Crafted from high-quality, crystal-clear acrylic, Theo Blocks invite children to build, stack, sort, and explore color and light in endlessly creative ways. Their generous square shape makes them easy for little hands to grasp while offering satisfying stability for bigger builds, think towers, patterns, and architectural masterpieces that won’t immediately topple.

The vibrant rainbow hues catch and refract light beautifully, encouraging light play, color mixing, and visual exploration. Whether stacked, lined up, or paired with sunlight streaming through a window, Theo Blocks turn everyday play into a mini science moment- no lab coat required.

Designed to seamlessly complement your existing collection, Theo Blocks pair perfectly with our other block sets and fit neatly inside our Busy Blocks, making them an ideal add-on or expansion piece for families who love versatile, mix-and-match play.

Acrylic Blocks - 2" X 2"

Not all acrylic is created equal. At Maison Rue, we use high-quality, crystal-clear acrylic specifically made for children’s play. Unlike mass-produced plastic toys, which are often opaque, cheap, lightweight, and designed for short-term use, our acrylic is dense, durable, and made to last.

Our Acrylic is CPC certified and safety tested to meet and pass all CPSIA standards, including testing for lead and phthalates. The clarity of our acrylic is intentional—allowing light, color, and transparency to become part of the play experience, while reflecting our commitment to refined materials and thoughtful design.

Strong yet luminous, acrylic offers a modern alternative to traditional plastic toys—one that feels substantial, safe, and beautifully made for open-ended play.
