II. The Top 10 Bestselling Styles: Featuring ACG Essentials

We’ve categorized the hottest trends into visual effects, material focus, and structural innovation to show you exactly how to capture the attention of collectors.

A. Material and Visual Effects Trends

 01. Glitter Epoxy Acrylic Charms (The Fan Artist Staple)

What It Is: These are transparent acrylic keychains where the printed design is protected by a layer of epoxy resin, often featuring suspended glitter, holographic particles, or foil. Why It’s Hot: The result is a glossy, domed surface that catches the light and sparkles, giving a high-end, visual pop to simple 2D illustrations. It is the most accessible and popular style among independent fan creators.

 02. Shaker Keychains (The Interactive Novelty)

Shaker Keychains

What It Is: This highly coveted style involves creating a multi-layered housing (usually acrylic or PVC) that is partially filled with liquid, oil, or tiny, loose pieces (like mini-charms, glitter, or beads). When shaken, the small items move freely.

Why It’s Hot: The extreme interactivity and cuteness factor make it an instant collector’s item and a viral hit on social media.

03. Double-Layered 3D Acrylic

What It Is: Instead of flat printing, two or more layers of acrylic are cut and stacked (with a slight offset) to give the 2D illustration a sense of depth and dimension.

Why It’s Hot: It offers a more premium, structured look than a single layer, creating a “shadow box” effect that suggests quality without the higher cost of a true metal mold.

 04. Hard Enamel Metal Badge Keychains

What It Is: Manufactured similarly to fine jewelry pins, these metal keychains feature crisp lines, polished metal, and enamel colors that are polished flush with the metal edges. Why It’s Hot: This style conveys maximum prestige and quality. It is perfect for replicating guild crests, family sigils, fictional weapon logos, or uniform badges from within the anime world, appealing to fans who want a high-status collectible.

B. Functional and Structural Innovations

05. 3D Soft PVC Figurine Keychains

What It Is: Flexible, durable keychains made from soft PVC (rubber-like vinyl) that allow for the creation of adorable, multi-layered, three-dimensional Chibi characters or mascots. Why It’s Hot: PVC is resilient, water-proof, and excellent at reproducing the soft, squishy look of Q-version characters. They have a satisfying tactile feel and are virtually indestructible.

06. Mini Weapon/Prop Model Keychains

What It Is: Small, detailed metal keychains that replicate iconic in-anime items, such as swords, magical staffs, rings, or game inventory items.

Why It’s Hot: Fans crave tangible representations of the tools their favorite characters use. These items are often sold as blind boxes due to their collectability and detailed craftsmanship.

07. Standee Keychains

What It Is: A dual-purpose design where the main character charm can be detached from its base and clipped onto a keyring, while the base itself functions as a small desk stand (standee).

Why It’s Hot: It fulfills both the “display” (on a desk) and the “carry” (on a bag) needs of the collector, maximizing utility.

08. Meme or Dialogue Bubble Keychains

What It Is: Keychains shaped like classic anime expressions, reaction faces, or dialogue bubbles (often containing a memorable catchphrase or quote).

Why It’s Hot: This style captures the cultural zeitgeist and online fan humor, making it highly shareable and immediately relatable to the fandom.

C. Accessory and Connection Upgrades

09. Detachable/Split Couple Keychains

Split Couple Keychains

What It Is: A single design that separates into two complementary pieces (often using magnets or specialized clasps), designed for partner characters (CPs) or best friends.

Why It’s Hot: They foster a sense of community and connection, allowing friends or partners to share a piece of the merchandise.

 10. Upgraded Colored and Shaped Clasps

What It Is: Replacing the standard, simple split ring with premium hardware like star-shaped clips, heart-shaped clasps, or colorful metal D-rings. Why It’s Hot: Hardware upgrades are a simple, high-impact way to improve the overall product quality and aesthetic. A customized clasp instantly signals a high-quality, professional piece of merchandise.

III. Summary and Customization Advice
