The 7021B is made for sunglass displays where the look of the stock matters as much as the quantity. Its open white frame holds 40 pairs on slim arms, so each style is seen in outline against the space around it.
Optical practices with bright, modern waiting areas use it to present a sun range without adding a solid block of furniture to the room. Patients see every frame clearly as they wait, and optical assistants can give each side to a brand, a shape or a lens colour.
Boutiques, concept stores and department store accessory areas place it near windows or under strong lighting, where the open structure lets the light reach each pair. Fine metal frames, gradient lenses and pale acetates keep their detail, which suits higher-value and fashion-led ranges.
Pharmacies and gift shops with a light, clean interior also suit the format, as the white frame blends into pale walls and fittings and keeps the eye on the sunglasses. In a smaller shop, the slim structure keeps the floor feeling spacious even when every arm is filled. Travel retailers and resort stores with glass frontages can also stand it close to the window, where passers-by see the whole range from outside.
In each setting, staff hang a pair on each arm, arrange the four sides and turn the tower to restock from one spot. Customers turn it, lift a pair from its arm and try it on. Because it needs no power, the 7021B can stand wherever a light, open sunglass point is wanted.
