7-Piece Crystal Clear Pastel Rainbow – Lucite Acrylic Building Blocks

Fill playtime with color, light, and beautiful reflections with our 7-Piece Crystal Clear Pastel Rainbow.

Made from highly transparent Lucite acrylic, this seven-piece nesting rainbow features a dreamy palette of soft pastel colors. Each individual arch is crystal clear and beautifully polished, allowing light to pass through and create glowing reflections, colorful shadows, and overlapping shades.

Place the rainbow near a sunny window and watch the colors come alive. As sunlight travels through the transparent acrylic, the pieces cast beautiful rainbow-colored reflections across floors, tables, and walls—turning a simple building toy into an engaging exploration of light, color, transparency, and shadow.

The seven graduated arches can be nested together to form a complete rainbow or separated for stacking, balancing, building, sorting, and imaginative play. Children can create tunnels, bridges, sculptures, small-world landscapes, or combine the arches with wooden blocks, acrylic blocks, figures, and other open-ended building materials.

The substantial 1-inch / 2.5 cm thickness also allows the pieces to stand securely on their own, making them especially versatile for three-dimensional construction and creative arrangements.

With its smooth transparent finish and soft pastel palette, this rainbow is just as beautiful displayed on a shelf as it is incorporated into everyday play.
