No matter which framework style you decide to use, part of the value of the framework is protecting, with the ability to protect certificates. Certificates are usually made of relatively strong paper or parchment materials, which may cause discoloration, water damage, tearing and other problems in the long run, and paper products can fade easily under ultraviolet light. It is important that the glass or acrylic plate that protects the certificate can be treated to prevent ultraviolet rays from passing through. You can also use DIY, but try not to buy non-professional basic store-bought frame from a big box store. Because low-quality frames actually make your certificate more likely to be compromised over time.
