These are also used in Bakeries for Bread and Pastries. These are just some of the uses display cases provide in general. Display cases for customer interaction are, by design, counter-height affairs. This is where shoppers head to for help with an item or to pay for their purchase. Access to items inside the cabinets can be either via the front or behind. If your store sells expensive merchandise like jewelry, electronics, or other high-end products, you will want the locking cases for security's sake. Free-standing display cabinets feature almost all-glass construction that allow customers to encircle the fixture while browsing. Thanks to their multi-level shelving, these cases can hold a lot more items than counter models, making them good choices for gift shops, antique stores, and other businesses that sell a lot of smalls.
