Red paper is usually bought in bridal shops, stationery stores, small shops and supermarkets. There will be red paper at the stationery counter of a stationery store or a shopping mall. If there is no red paper, please consult the boss who sells stationery. If you can't find it locally, you can buy it online. Copper is mainly used for writing Spring Festival couplets, making lucky money bags, greeting cards, hand-made origami and paper-cutting.
