Beldona AG is the market leader for lingerie and swimwear in the Swiss retail sector. In April 2019, Beldona opened a new store in Aarau (Switzerland), which was fitted with the wall display system Xero 4.Xero 4 is only discernible as a vertical groove in the wall. Xero provides a discreet elegant background, which highlights the merchandise display. Different merchandise supports, such as front arms for hanging goods or shelves with lighting, can be easily inserted into the groove. Due to Xero's vertical structure, merchandise supports can be flexibly adjusted in height to make optimum use of space and accommodate a changing array of products.
