Nothing serious. There's nothing wrong with losing the cover. Don't be overly anxious. We usually need the original diploma, and it doesn't matter if we lose the cover. After all, we don't look at the cover when checking or verifying the information, so don't worry.

However, the next time you encounter this situation, you should take care of yourself and protect your important things. After all, you just lost the cover this time, which is not very important. If you lose something important next time, you may regret it. So take good care of your things.

It doesn't matter if the cover of your diploma is lost. Protect your diploma.
