KOAICS Rainbow Crystal Acrylic Cubes – 16-Color Sensory Stacking Blocks for Kids

KOAICS Rainbow Crystal Acrylic Cubes

Meet a vivid set of 16 translucent gem blocks designed to captivate little hands and curious minds with color, light, and tactile exploration. Each cube measures 2.5 cm on every side and is hand-sanded to a smooth, premium feel in a durable acrylic finish.
