I bought this set in RED and it was super easy to see on the luggage handling belt.
My 5 year old pushed the smallest piece while my 10 year old pushed the medium sized piece with ease.
The 4 wheels are a huge plus in manuevering them around the airport.
They each fit into each other so I only had to find a place in the hotel room for one piece of luggage - wonderful !
I am so pleased with this set and highly recommend it - you won't be disappointed.
