Guidecraft Sensory Rainbow Blocks - 18 pc. set

This is an 18 piece set of hardwood block frames with inset transparent acrylic windows. Six blocks are filled with shimmering water, six with sand and six with crystal beads. The assorted shapes are sized to standard unit block measurements, so they stack and combine with other classic building blocks for open ended construction.

Each block catches and filters light through coloured plexi windows while the water, sand and bead interiors shift and shimmer as children tilt them. Combining blocks mixes new colours and gentle sounds, and stacking them in different orders builds new shapes every time. This engages sight, sound and touch all at once.

Yes. The transparent acrylic windows and translucent fillings are made for light table activities. Placed over a light source, each block glows and the colours blend where they overlap, helping children explore colour mixing, visual perception and hand eye coordination during calm, focused play.

The set contains 18 assorted block shapes. Six are filled with shimmering water, six with coloured sand and six with crystal beads, giving three distinct sensory effects. The mix of shapes lets children build towers, walls and patterns while comparing how each type of filling moves and looks.

Guidecraft recommends the Sensory Rainbow Blocks for children aged two and up. The smooth hardwood frames are chunky and easy to hold, making them suitable for toddlers exploring cause and effect as well as older children building more detailed structures and experimenting with colour and light.

The frames are smooth, hard wood in primary colours, fitted with transparent plexi windows. Inside, the blocks hold shimmering water, coloured sand or crystal beads sealed behind the acrylic. The solid construction stands up to repeated stacking, knocking and everyday block play.
