Made from 100% Cotton, this white t-shirt features a beautiful illustration of Star Wars stalwarts Darth Vader and Luke Skywalker, holding aloft their exceptionally laser-y swords and....completely unaware of the others' presence. Yup. Probably a good thing, since...well, one abandoned the other to embrace eternal darkness and wreak extreme havoc across the known Galaxy, while.....the other? The other just wanted to...shoot womprats or..or throw rocks at a painfully prevaricating android. Yup. But let's cut to the chase; the reason you're really here: This t-shirt changes color! HOW!!?? Well, this design is printed in a light sensitive, UV-Ink, which changes or adds color when exposed to direct sunlight. NEATO! Pretty sure Imperial tech can't match it. Nope.
