It may be just for kids but… err… well… it’s sort of cool. I could use one of these. Wonder how bad it would be at Airport Security? But, this does seem like worth the hassle.
Now… WHY wouldn’t you make this a bit bigger? It may be fine for some short trips but they should make it in bigger sizes. Perhaps an entire luggage set. Make it a bit pricey so not everyone is off getting one of these.
Actually… scrap the idea of the luggage set. I doubt I would want to check-in my Batmobile luggage. Losing one of these would be most upsetting.
