While standard-size enclosures from conservation suppliers will normally be sufficient to provide support and protection for collections, sometimes custom-made enclosures are needed. Conservation suppliers are generally willing to work with you to produce enclosures if you have a specialized need.
The most frequently encountered custom enclosures are book boxes. These can be made by a conservator or by bookbinding companies. They are generally used for books of significant value that need a box fit exactly to size to avoid abrasion from the book shifting inside a box that is too large or damage to the book's joints and edges by a box that is too small.
