We love to find fun cosplay products from Japan, and one of the most popular products we've ever carried has been the Necomimi Nuerowear cat ears, which work by picking up your brain waves, moving just like a cat's. The unit work great, sensing changes in your brain waves as well as circulation. At the summer's anime conventions we sold them, and whenever someone would approach the ecchi side of our booth we'd laugh as the ears shot straight up, just like a real cat. We recently restocked the U.S. version of the Necomimi Cat Ears, and today we got in the alternate cat ear coverings, which allow you customize your cat ears so they're special. So cute!
