Collection: Nuba Stitch Series (DU03-GR).
Color: Charcoal Grey Exterior with Pale Pink or Cream Interior.
Premium PU leatherette with real thread sewing and a spring-loaded clamshell mechanism.
Upgrade your jewelry presentation with Winnerpak’s DU03-GR Collection. This collection mixes the contemporary look of charcoal grey packaging with classical craftsmanship. These boxes, with their characteristic arched top profile and visible perimeter sewing, provide a tactile, high-end experience that plastic boxes cannot match. As a direct jewelry box manufacturer, we offer these premium cases at a competitive wholesale price.
Why Choose the DU03-GR Series?
1. Authentic stitching detail.
Unlike printed imitations, the DU03-GR has true thread stitching along the lid’s edges. This “sewn leather” style conveys quality and durability, making it an ideal choice for firms that sell heirloom-grade pieces, wedding rings, and fine silver.
2. Modern Grey Aesthetic
Grey is the new neutral in luxury shopping. It’s less harsh than black and more modern than brown. The deep gray leatherette exterior creates a stylish backdrop that highlights both gold and silver jewelry.
3. Protective Hard Shell Construction
These are sturdy jewelry boxes designed to last. The solid core protects delicate products during delivery, and the powerful spring hinge guarantees that the box clamps shut securely—an important characteristic for engagement ring packaging.
4. Soft Interior Lining.
The interior is completely lined with a soft, velvety fabric in a contrasting light tone. This protects delicate diamonds from damage and gives an extra touch of beauty when the buyer opens their gift.

Discover the DU03 Nuba Series, which represents the pinnacle of classic luxury in jewelry packaging. This line, produced directly by ChinaJewelryPack, goes beyond ordinary paper packing to provide a durable, high-end “leather-look” experience. These boxes, with a characteristic domed top and beautiful perimeter stitching, are made for jewelers who want their packaging to be saved and treasured as much as the jewelry inside.
Distinctive Product Features
1. Premium “Nuba” Leatherette Finish.
The exterior is wrapped in our proprietary Nuba PU leather, which has a beautiful pebbled grain pattern. This material has the delicate touch and resilience of genuine leather, making it more resistant to scratches and wear than typical paper boxes.
2. Signature Arched Top with Stitching
The DU03 series’ distinctive feature is its convex, arching lid, which lends great apparent height and grandeur to the display. This curvature is highlighted by precision perimeter stitching (tone-on-tone), a handcrafted touch that conveys exceptional craftsmanship to your customers.
3. Luxurious contrast interior.
Opening the package reveals a stark contrast. The interior is lined with a soft, velvety material in a delicate Pale Pink or Cream color, which looks wonderful against the darker exterior colors (Black, Grey, or Brown). This high-contrast design makes your gold and diamond jewelry stand out from the moment you open it.
4. Professional Retail Display.
These are more than just storage boxes; they also serve as display tools. The sturdy spring-hinged mechanism keeps the box open at the ideal angle for a spectacular presentation. The internal padding is custom-cut to keep rings erect, necklaces correctly draped, and earrings secure.
