The 100% cotton TMNT Michelangelo Kids Costume T-Shirt will allow that little mutant in your life to become their favorite Hero in a Half Shell Michelangelo! Oh did I say mutant? I meant little child. I often get the two confused these days which makes for awkward conversations with my family. Printed on both sides the TMNT Michelangelo Kids Costume T-Shirt has the underside of the shell on the front while the back of the shirt shows the shell! That may be a little confusing but you'll get the jist of it by that picture over there.
