This is a set of 4 thermal paper rolls, each with a width of 58mm and an outer diameter of 30mm. Made in China. Compatible with mini printers that use 58mm wide, 30mm diameter thermal paper rolls, such as Peripage, Phomemo, and Paperang. Also compatible with toy cameras that print on roll paper, such as AMKOV. Compatible with receipt printers like Square Terminal and VEGA3000 (confirmed). Compared to Japanese brand paper rolls, the color is blacker and the paper is thicker. The length is 6.7m and it can be preserved for 5 years. The actual width is 55.5mm, making it compatible with slightly narrower models. Please note that this is not sticker paper. If you have any questions, I can help you with category suggestions. * For Phomemo, insert the roll paper directly without using the holder. Set it so that the printing surface faces up. * Not compatible with toy cameras that use 25mm diameter roll paper. #Phomemo #SquareTerminal #ThermalPrinter #MiniPrinter
