Lovely little set of 4 toys.each toy comes in 3 parts which fit together with a magnet.you can mix the pieces and make different kinds of toy cars,plane,train and speedboat.my little toddler doesnt like the music so i will be removing the batteries.i also dont like the tune as its just one tune on each one and same tune which is very annoying.other than that its well made and a great set for small children.
