Upscale wine accessories are merchandised from upscale glass shelves. To complete the outfitting an innovative Bottom-load, Backless, Grip-clip Label Strip, with the grip uniquely positioned behind the window. This is a “backless” design with no rear to the overall profile, just the clear window front. The label inserts behind the clear window, with only the grip at the top to hold it in place. It looked great, and surely saved materials and cost. But it might not fare well in high humidity environments where paper labels are prone to curl.
