If you think recycled paper will be worse than usual, you're wrong. Recycled paper is thin, light, durable and environmentally friendly. If previously, people often mistakenly think recycled paper is poor quality, now, this thinking is completely changed. Despite being a recycled product, this paper is of equal quality to newly manufactured paper. You can totally believe that recycled paper is still used for convenient applications such as wallets. Don't forget to add a small note on your wallet, like "This product is printed on 100% recycled paper". Such small notes, but will make your wallet more civilized in the eyes of partners and customers. Every time you use recycled paper, let everyone know to contribute to raising awareness about the environment!
