This ball is great!
Both my 3 year old son and myself have been.playing with it and find it good.
You can push a ball into the empty hole next to it and mix the colours up. There are rings around the holes corresponding to where the correct colours should be a and has an empty hole with no colour.
It is really well made and robust. My little one has dropped it quite a few times and it's still perfect!
Great little gift for any age
