Coloured Hollow Blocks

SEE THE WORLD IN A DIFFERENT LIGHT

This set of 4 blocks features vibrantly coloured centres.

• red
• yellow
• green
• blue

Using sunlight, try getting the colours to reflect onto different surfaces. Great for playing traffic lights. Same size as the eighth hollow blocks so a perfect complement to the hollow block set. Or use with a periscope to look round corners in different colours.
