Japanese car accessory company, Junction Produce, makes things like leather neck pillows, privacy curtains, and fancily tied knots to adorn your favorite VIP styled automobile. In 2011, when apparently no one had a good camera handy, they collabed with Hello Kitty to make air fresheners and plush toys. While these have been long discontinued, there's a couple on eBay right now you can snag.
