This is an interesting idea and has a few applications. It’s all timber – 4 blue and 4 read skittle that nest in a base. Each peg has a different weight (4 different weights per colour)- and you try and find the matching weight in the other colour. The pegs also have a self-checking option – as each peg has a different sized circle grooved in its base (so you can find the match in the opposite colour by checking the bases). Each peg is approx  7.5cm x 4cm and are easy to grasp/hold. These are ideal for learning and comparing weight, for sensory processing/sensory awareness, visual impairment, playing blindfolded games and special needs. 24x14xcm approx For 3yrs+
