Trade show exhibitors and jewelry sales people need glass display cases that are light, well built and easy to carry. Since trade show booths include as standard items a couple of tables with chairs exhibitors only need to bring with them the top glass display area portion. This has proved to be a practical and economical solution to their merchandise presentation in many locations. Due to the very tight business conditions of the last few years retailers have chosen to purchase only glass display cases tops instead of full showcases. It saves them money on the cost of their display cases in as well as on the transportation costs. Afterwards they will have their cabinet bases made by a local wood worker or carpenter. The savings look attractive at first. Though the costs of having locally made cabinets to match might end up being surprisingly high. Also it is not easy to match the quality standards of the two components. Nevertheless the trend towards the purchase of glass display cases tops is persistent and is nowadays a specific category for all glass display showcases manufacturers.
