Standard boxes are square. Exceptional packaging has a shape.
The Winnerpak TULP-NJ Series challenges standard flat-top packaging. This box has a softly arched (domed) lid that replicates the silhouette of classic leather cases, giving it a high-end feel for a fraction of the price.
This is a sturdy folding carton made of 2mm Rigid Greyboard. It is a permanent storage container for your customer’s most valuable items. The exterior is covered with Textured Aqua Blue paper that feels like linen canvas, while the interior is decorated with Jet Black Velvet to set a dramatic scene.

Soft curves. Sharp contrast.
Break away from the usual square box. The Winnerpak TULP-NJ Series features an elegant Arched Lid Design (Curved Top) that resembles the silhouette of classic luxury cases, but is made entirely of sustainable rigid board and paper.
This box, wrapped in a characteristic Textured Aqua Blue (similar to the world’s most recognized jewelry company), combines fresh pastel tones with a stunning Jet Black Interior. This high-contrast combination was created expressly to highlight the brightness of Sterling Silver, White Gold, and Diamonds.
Why Choose the TULP-NJ Series?
The “Domed” Profile: The softly curved top increases height and perceived value, distinguishing your brand from competitors who use flat, generic boxes.
Tactile Finish: The outside paper has a delicate Cross-Hatch / Linen Embossing that adds a premium non-slip feel.
Invisible Magnetic Snap: A hidden magnet in the front flap secures the curved lid with a pleasant snap.

Frequently Asked Questions (FAQ)
Q1: Can I get my brand printed on the curved surface?
A: Yes! While the surface is arched, our sophisticated hot-stamping and screen-printing machines can precisely place your brand to the center of the lid. We recommend black or silver foil to provide the best contrast against the blue paper.
Q2: Does the magnetic closing work well with the curved lid?
A: Absolutely. We employ a stronger hidden magnet in the front flap. The engineering is accurate enough that the curved lid “snaps” flush on the base every time, keeping it closed during transport.
Q3: May I alter the interior color to white?
A: Yes. As a factory, we can modify the inside. However, we prefer Black for this series because it gives the best contrast with the Aqua Blue exterior and hides jewelry tarnish better than white.
Q4: Is the TULP-NJ-08 deep enough to accommodate men’s watches?
A: Yes. The TULP-NJ-08 stands 55mm tall and is specifically suited for clocks. It comes with a velvety velvet pillow that fits both men’s and women’s watch straps.
Q5: Are the boxes packed flat?
A: No, these are rigid setup boxes. They are sent fully built, with foam inserts inside. This means more delivery volume, but no assembly effort for your team.
