Project Overview
In this case study, we delve into the design and manufacturing journey of a unique, story-driven enamel pin that captures the essence of peace, nature, and light. Centered around a whimsical frog lounging in a greenhouse, this project seamlessly blends premium enamel finishes—such as stained glass enamel, glitter, and pearl enamel—to create a product that’s both playful and refined.
This frog greenhouse enamel pin was envisioned as a collectible art piece, designed for customers who appreciate high-quality craftsmanship, tactile detailing, and emotionally resonant imagery.
Client Vision and Design Goals
The client approached us with a detailed concept:
A relaxed frog resting among greenery inside a glass greenhouse, lit with dreamy natural light, surrounded by vibrant plants and whimsical flowers.
They wanted the final product to:
- Feature translucent enamel elements to mimic real glass panels.
- Use glitter enamel to add life to flowers and plants.
- Include pearl (no swirl) enamel for subtle highlights.
- Have a polished gold-plated finish for luxury appeal.
- Include a custom backstamp and be individually packaged for online sales.
The pin needed to balance charm with clarity—delivering a clean and elegant finish without compromising on visual storytelling.

Production Process
- Digital Proofing & Color Mapping
A professional proof was prepared using Pantone-coded colors, glitter zones, and finish labels. Transparent sections were carefully outlined to maintain structure while allowing light to pass through.
- Molding & Die Casting
Using a CNC-engraved mold, the base metal was die cast with precision-cut edges and inner cutouts. This ensured a stable yet lightweight foundation for enamel application.
- Hand-Filling & Enameling
Each pin was hand-filled with high-quality enamel. Translucent and glitter colors were injected carefully to prevent mixing. Once filled, the pins were baked to solidify the enamel and lock in the clarity and sparkle.
- Polishing & Plating
The pins were machine-polished to achieve a flat, smooth surface where the enamel meets the metal. A rich gold finish was electroplated for a vibrant, elegant look.
- Assembly & Quality Control
Each pin was fitted with two black rubber clutches to ensure secure wear. A custom backstamp was added for branding, and every piece underwent thorough inspection before being individually packaged.
Client Feedback
The client was thrilled with the result and particularly praised the lighting effect through the stained glass enamel:
“We couldn’t believe how beautifully the transparent sections turned out. The way the glitter sparkles and the frog’s calm expression come through is just perfect.”
Their enthusiasm led to discussions on follow-up seasonal pins, expanding the “frog-in-environments” theme into a collectible series.
Key Results and Learnings
- The stained glass enamel technique proved ideal for conveying transparency and softness in nature-themed designs.
- Glitter enamel added motion and sparkle without overpowering the composition.
- The combination of hard enamel, clear enamel, and custom cutouts produced a premium collectible pin that felt both solid and artistic.
