Everything we sell are "Print On Demand" products. This means the shirt or accessory you are buying isn't made until you order it. This allows us to offer a wide array of cool products with as many fun designs as we can come up with, without the high overhead that would come with having a warehouse full of premade products. When you buy a shirt, you get to choose the size and color that you prefer. So you get the SoNERDWear you want, your way.
