The notebags combine paper bags with memos. From the perspective of secondary use and psychological suggestion, this is a redesign of the standard paper bag so that it can be torn into a certain number of memos. The bottom of the paper bag forms a storage box to hold the memos. After repeated tests, the designers chose 100-gram brown kraft paper as the main material. This product is aimed at awakening the public’s environmental awareness, guiding users through tearing the paper bags and turning into memos to achieve the secondary use.
