Lego have been doing this for years, build-able toys, which can be made into alsorts,(a van for the 'bad guys', as my grandson said!) from pieces which are colourful and durable.Easy to assemble with easy to follow instructions. This kit is no exception, but it does help to have all the pieces, my kit just had one bit missing, but Lego themselves offer the 'missing part?' service, one or 2 items, sent free of charge. Great fun.
