A nice way to cap off a restoration is to have a clam shell box made for it. These cases are custom made to to the dimensions of your book to ensure a safe fit. They are constructed with all acid-free materials so your book will have a safe storage place. This is also a solution for items that you want to keep “as is” but store safely.
Enclosures are also available for those important family documents. The thin portfolio has interior corners to safely hold your doucment in place.
For those books that you still wish to see the spine, but want to protect, a slipcase is a great compromise. This is also a great solution for multiple books!
