Avoid storing the certificates inside the folder without protective interleaving for extended periods, as prolonged contact may cause the paper to deteriorate over time. After signing, carefully lift both sheets out of the folder by the corner folds and place them into the provided polypropylene protective sleeve included with your order. For added protection, it is encouraged to wrap both certificates in the acid-free tissue paper provided with your packaging before placing them into the sleeve or folder. You may also choose to store the certificates in other archival-grade materials, if preferred, to further support long-term preservation.
