Wonderful designs and so many stickers! After a lot of research we decided these would be the best for our boy's room and we were not disappointed. They go very nicely with the trains and tracks set as the style of drawing matches.
A slight word of caution - these will look at their best applied to a white wall. Our son's room is a pale blue and this does affect the colouring ever so slightly as they are not 100% opaque, more about 90-95%. It's nothing major and not a bother for us at all, most people probably wouldn't even notice but I thought someone might find this information helpful. I think if you were to apply them to a dark coloured wall you would definitely begin to notice.
