There are plenty of smartphone covers and screen protectors out there, but they all leave your phone’s most thumbed area, the home button, exposed. That’s where the stylish smartphone panties or pantsu come in. They stretch over the base of the device and cover it private parts.

If you haven’t figured it out already, these cheeky accessories were invented in Japan, by the world’s largest toy-maker, Bandai. They lacks any kind of functionality, and actually make it really hard to operate your phone, but Japanese teens thought they were cute and snatched them up quickly when they first hit the market back in march. Following the SmartPants’ success, Bandai has recently launched a new range of silicone smartphone underwear, featuring all kinds of patterns, from animal print to banana and Mount Fuji. There are also a variety of models, from skimpy bikinis to jockstraps and briefs. The stretchy gadget undies are made of silicone to fit most smartphone models and cost ¥200 ($2) a piece. You can find them in Gashapon machines (Japanese vending machines) across Japan. If you’re interested, sets of 7 panstu are available on the J-Box online store for $38.50. Kind of expensive for a useless accessory, but they’re guaranteed to make your phone stand out.
