"This is a great box set and my 4 year old (going on 5) really enjoyed building the sets. All she needed was a bit of clarity on how to fit some parts otherwise she built them all herself.
There are 3 ‘themes’ in the box and each theme can be built 2 ways. In order to build the other version of a theme requires the parts to be deconstructed almost completely but that adds to the product life and fun! I particularly like the detail in the music theme and my daughter enjoyed building the individual instruments for it."
