Collecting & Care

In the vibrant world of anime and gacha game collecting, acrylic stands and PVC figures usually take the spotlight. They are colorful, highly detailed, and capture our favorite characters in dynamic poses. However, as collections mature, many fans find themselves drawn to a different kind of merchandise—something with literal and figurative weight.

Welcome to the premium tier of collecting: Metal Merchandise. From the satisfying heft of a commemorative coin to the intricate 3D relief of a zinc alloy faction badge, metal merchandise offers a tactile experience that plastic simply cannot match. It feels like a genuine artifact pulled straight from the worlds of Honkai: Star Rail, Genshin Impact, or Wuthering Waves.

But not all metal is created equal. Why do some badges rust while others shine eternally? What is the difference between tinplate and zinc alloy? In this deep-dive educational guide, we will explore the science and craftsmanship behind official metal merch, highlight some of the most stunning pieces available at Bahomu, and teach you how to preserve them for a lifetime.

The Science of the Forge: Tinplate vs. Zinc Alloy vs. Enamel

When you browse for badges (often called "pins" or "buttons"), you are usually looking at three distinct manufacturing processes. Understanding these will help you appreciate the value of your collection.

1. Tinplate (The Classic Button Badge)

Tinplate (马口铁) is the most common material for standard anime badges. The process involves taking a piece of printed paper, placing it over a slightly convex metal dome, and sealing it with a clear, protective PET film (often giving it a glossy or matte finish).

• The Pros: Tinplate allows for perfect 1:1 reproduction of complex, highly colorful 2D character art. It is lightweight and affordable, making it the go-to choice for building massive, vibrant "Ita-bags."
• The Cons: Because it relies on a paper insert, it lacks 3D texture. If exposed to extreme moisture, the metal backing can eventually oxidize (rust).

2. Zinc Alloy & Enamel (The Premium Artifact)

If you see a badge described as "Metal Badge," "Brooch," or "Commemorative Coin," it is likely made of Zinc Alloy (锌合金). Instead of printing paper, the manufacturer creates a steel mold and casts the liquid metal into a 3D shape. After casting, the recesses in the metal are often filled with colored liquid enamel (烤漆/珐琅), which is then baked until hard.

• The Pros: Incredible durability, significant weight, and a luxurious 3D texture. These items feel like real jewelry or in-game currency.
• The Cons: More expensive to produce, and usually restricted to logos, emblems, or stylized character silhouettes rather than full-color illustrations.

Showcase: The Masterpieces of Metal

Let's take a look at how HoYoverse and Kuro Games utilize these premium manufacturing techniques to create lore-accurate masterpieces.

The Executive Authority: Honkai Star Rail Stoneheart’s Badges

Few factions in the galaxy command as much respect (and fear) as the IPC's Ten Stonehearts. To represent their immense wealth and power, standard acrylic simply wouldn't do.

The Honkai: Star Rail Stoneheart’s Oath Ring Series Metal Badges are prime examples of high-end zinc alloy casting. Notice the deep 3D relief—the raised gold edges are electroplated for a brilliant shine, while the recessed areas are filled with dark, matte enamel to create stark contrast. Holding this badge feels like holding Aventurine or Topaz's actual IPC clearance credentials.

Lore-Accurate Relics: Wuthering Waves Metal Coins

Commemorative coins hold a special place in the collector's heart because they feel like "diegetic" merchandise—items that actually exist within the game's universe.

The Wuthering Waves Resonator Themed Metal Coin utilizes a specialized "antique plating" process. After the coin is minted, it is coated in a dark patina and then polished. The dark color remains in the deep crevices, highlighting every tiny detail of the Resonator's emblem and giving it a weathered, ancient appearance. It’s a tactile connection to the post-apocalyptic world of Solaris-3.

The Ultimate Hybrid: Quicksand Metal Badges

What happens when you combine the heavy, luxurious frame of a zinc alloy badge with the mesmerizing fluidity of a quicksand block? You get an absolute showstopper.

The Genshin Impact Iktomi Spiritseeking Scrolls Quicksand Metal Badge represents the cutting edge of merch manufacturing. A sturdy, intricately molded metal frame encases a sealed acrylic core. Inside, a mixture of cosmetic-grade oil and metallic glitter flows freely over the printed background. It is a stunning fusion of 3D metal craftsmanship and dynamic visual motion.

"I used to only buy acrylic stands, but the moment I held a zinc alloy faction badge in my hand, everything changed. The weight, the cold touch of the metal, the way the light catches the electroplated edges... it feels less like 'merch' and more like a high-end prop replica." — Bahomu Community Collector

How to Protect and Display Metal Merchandise

While metal and enamel are incredibly durable compared to paper or thin plastics, they still require specific care to maintain their museum-quality finish, especially if you live in a humid climate.

1. The Enemy is Oxidation: Never leave your metal badges or coins in damp environments. If you wear an enamel pin on a backpack and get caught in the rain, make sure to dry it thoroughly with a soft microfiber cloth as soon as you get inside.
2. Beware the "Green Gunk": Sometimes, the brass or copper elements in pins can react with the air, producing a green residue. You can prevent this by keeping your display area low in humidity, or by storing rare coins in airtight acrylic coin capsules.
3. Polishing: If an electroplated badge (like gold or silver finishes) starts to look dull, do not use harsh chemical metal polish, as it can strip the thin plating. A simple wipe with a dry jewelry polishing cloth is all you need to restore the shine.
4. Display Ideas: Metal badges are heavy and can cause thin fabrics to sag. If you are building an Ita-bag, use a sturdy, thick canvas insert. For desktop displays, magnetic floating frames or velvet-lined shadow boxes make metallic coins and badges look incredibly premium.

Frequently Asked Questions (FAQ)

Do metal enamel badges scratch easily?

Hard enamel badges are extremely durable, as the enamel is baked flat and polished smooth with the metal lines. Soft enamel has a textured feel where the metal ridges are raised. While both are tough, you should avoid tossing them loose into a bag with keys or coins to prevent micro-scratches on the polished metal.

How heavy is a typical zinc alloy commemorative coin?

Unlike standard arcade tokens, official anime commemorative coins (like those from Wuthering Waves or Genshin Impact) usually have a solid zinc alloy core. They generally weigh between 30g and 50g, giving them a very satisfying, substantial heft in the palm of your hand.

Can the liquid inside a Quicksand Metal Badge leak?

Official quicksand badges from brands like HoYoverse undergo strict quality control and sonic sealing processes. Under normal use and display, they will not leak. However, you should avoid dropping them onto hard surfaces or leaving them in direct, scorching sunlight (like a car dashboard), which can cause the acrylic casing to warp.

How do I attach a heavy metal brooch to my clothes without damaging them?

Heavy zinc alloy brooches usually feature double-pin backs or safety-pin style clasps to distribute the weight. We recommend attaching them to thick, structured fabrics like denim jackets, canvas backpacks, or lapels. Avoid pinning heavy metal merch to thin silk or delicate knit sweaters, as it may stretch the fibers.
