Imagine a kiosk that sells cell phone cases, but with some key modifications

Imagine a kiosk that sells cell phone cases, but with some key modifications. We will keep the glass urns in a rectangular format, where the cases are arranged in rows, visible from outside. However, Now the cases will be secured with locks on the top of the urns, that only the vendors inside the kiosk can open. The vendors are inside the kiosk, visible through the transparent urns. They can serve customers through small windows or openings at the top of the urns., where cases can be displayed up close without compromising security. Lighting is still important: LED lights inside the urns highlight the colors and designs of the cases, while the top of the kiosk has an eye-catching sign that attracts customers. I want the cases to look very attractive because of how they are being displayed., That is the main thing in the image and that there are several urns where the sellers are inside the rectangle and the buyers outside looking at the merchandise and interacting with the sellers. The urns that have the cell phone cases displayed should not be high., The maximum is about the waist of a person of one and a half meters in height.. And without any wall blocking the way so that customers can see the cases from any direction..
