All items in the store (excluding PDF magazines and 3D models) are printed on demand, which is why it may take a little longer to deliver them to you. We (sinobus.top) do not handle the sale of any items ourselves; all items are set to go through third parties that specialize in print-on-demand services such as “Printful” (for shirts and stickers), “Lulu” (for magazines,notebooks and calendars), and “cgtrader” (for 3D models). They handle all order processing and delivery. Sinobus.top receives a small percentage of the sales, which is used for domain, hosting, and website maintenance.
