Unusual or unique collectibles may need customized display cases for exhibition and storage purposes. It can be difficult to find a box display case of the right size for an irregularly sized die cast model, for example. Or a rosewood display case may be of the right size and material, but does not match the oak wood furniture in the room. Display cases need to meet exacting standards of aesthetics, material, size, and harmony with the existing dcor, and may be different from mass manufactured display cases. Custom display cases are manufactured in a limited number to fulfill such special display needs.

Custom display cases are made to order or customized on request. All large display case manufacturing firms have a department that specializes in customizing display cases on request. The display cases in these cases are not actually built from scratch on the customers request; they are simply modified with regard to size, background color, and material. For example, Potomac Displays customizes acrylic cases and tops of box displays with regard to color and even gives online price quotes.

Many small and big companies specialize in making entire display cases on request. Custom Displays is one such firm. Other small firms, either family run or single person affairs, make handcrafted, and unique pieces. These cases are slightly more expensive since each display case is one of a kind and a lot of painstaking manual labor goes into their construction. Many retailers of collectibles offer a service that provides display cases made to order. AMA Crystal cabinets are widely sold through Swarovsky retailers and advertised on websites for collectors.

The firms design display cases by the guidelines of the customer. Some firms, like Store Fixtures, even invite customers to draw what they have in mind and make cases based on the drawings.

Custom made display cases give a warm, human touch to the room that is different from machine manufactured assembly line goods. Customized display cases are just right for a trophy, flag or stamp collection of value that deserves a unique case to hold it.
