repairing damaged boxes

does trying to repair tears in old ruger boxes lower the value of the box? are there people on the forum that specialize in repairs? any tips on doing it or videos that show different methods of repairing?

Repaired boxes actually help a bit,, IF DONE RIGHT!

It's an art to fixing damages to cardboard. I do not know of any videos etc that show how. There are so many different types of damages,, that it can take all kinds of things to fix one. There are some of us who have made repairs,, but then there are repairs that are too "challenging" for us as well.
