Overview
This project exemplifies the intersection of creative storytelling and technical enamel craftsmanship. Centered around a beetle-like creature that opens up to reveal an adorable inner egg, the hinged enamel pin was designed to be more than just a wearable item—it’s an experience. With dual-layer construction, magnetic closure, and precision detailing, this piece brought to life a playful concept with a premium feel.
The result? A charming interactive pin that feels like a hidden treasure every time it’s opened.
Pin Design Details
These pin design details included:
The design was inspired by a weevil—a blend of beetle and nut imagery—with the top half acting as a shell or carapace. When opened, it reveals a happy, egg-shaped character with facial features and sparkles. The client emphasized the need for smooth mechanics, durable wear, and collectible appeal.
Design Preparation
The initial sketch was clean and precise, showing the layered structure with front and back views. The pin was divided into two parts, each with defined color zones. Important design elements included:
- The top layer: hard enamel+printing
- The bottom layer: hard enamel
- Backstamp: the client’s logo, “CHENTOMOLOGY,” was clearly carved for branding.
- Magnet Area: The inner curve of the top piece contained a recessed 6×0.8mm cavity to embed a 5mm round magnet, aligned with the lower piece to enable a clean “snap shut” motion.
Some Steps
Our production team followed a meticulous sequence to bring the design to life:
- Mold Development
Using engraving machine, we created 2D molds for both pieces.
- Enamel Filling
- We used hard enamel for both pieces to create a durable, glassy finish.
- Pearl powder and translucent enamel
- Wet Grinding
- Polishing & Plating: The pin was polished to a mirror shine and gold-plated.
- Printing
- Assembly & Packaging
Rubber clutches were added to the back of this pin. Each pin was packed in pvc bag+bubble bag.
Client Feedback
The client provided enthusiastic approval throughout the proofing process. After receiving the final production sample, they shared:
“Our client said: ‘The hinge action is perfect! The magnet gives such a satisfying snap, and the colors turned out even better than we expected. It’s so cute—people can’t stop playing with it.’”
Their delight with the pearl finish and magnet placement underscored the importance of balancing interactivity with quality craftsmanship.
Some Highlights
- The shimmer of the pearl enamel under light.
- The satisfying opening action.
- The delight of the hidden egg inside.
Why This Project Stands Out
This hinged enamel pin is a rare blend of engineering and emotional design. It proves that lapel pins can be more than static collectibles—they can be tactile, surprising, and story-driven.
With a well-executed hinge, hidden magnet, and layered construction, this design showcases how creative ideas can transform into real, wearable products with personality. It’s ideal for:
- Artist merch
- Collector drops
- Kickstarter exclusives
- Enamel pin box subscriptions
Conclusion
From concept to completion, the “Weevil Eggshell Surprise” pin demonstrates the potential of enamel craftsmanship when paired with interactive design. Our team brought this playful vision to life using industry-best techniques, clear communication, and an eye for detail.
