# Why Fandom Collectibles

> Understand why Iruka starts with K-pop photocards, how fandom collectibles differ from TCGs, and how the category can expand.

> **Status: Live documentation** - This page explains Iruka's product thesis
> using published market signals. It does not claim commercial traction,
> guaranteed card appreciation, or live physical custody.

## Category Thesis

**Iruka is Korea-first infrastructure for physical fandom collectibles,
starting with K-pop photocards.**

K-pop is the entry category, not the end state. Iruka is building one verified
flow for physical collectibles that can later support officially issued trot,
cheerleader, and sports cards:

**Vending → Reveal → Vault → Marketplace → Redemption**

## Why K-pop First

Published data shows that physical collectibles are already a meaningful part
of K-pop fandom activity.

The Korea Consumer Agency also found that buyers seeking random goods bought
the same album **4.1 times on average**. Iruka does not treat duplicate album
purchases as the product. Its commercial direction is to publish the eligible
physical card pool and odds before a collector opens a pack.

## What The Data Does Not Prove

Category growth does not mean that every photocard appreciates. A card can
remain inexpensive or have too little completed-sale evidence to support an
estimate.

Iruka treats value as item-specific. Relevant inputs include:

* Official issuance and exact card variant
* Artist, member, release, event, or purchase benefit
* Distribution scarcity and observed collector demand
* Physical condition and third-party grade when applicable
* Comparable completed sales, sample count, currency, and snapshot time

Iruka does not present estimated value as a guaranteed sale price, return, or
future liquidity.

## Fandom-native Identity

Gameplay-led cards are often organized around a game, set, card number, and
play attributes. Iruka's category model is organized around the identity and
distribution history of a physical fandom item.

| Identity layer    | Iruka record                                                                             |
| ----------------- | ---------------------------------------------------------------------------------------- |
| Category          | K-pop, trot, cheerleader, or sports                                                      |
| Subject           | Artist or team and member or player                                                      |
| Release           | Album, season, event, tour, or product release                                           |
| Distribution      | Album inclusion, preorder benefit, event benefit, official merchandise, or licensed drop |
| Physical evidence | Exact front and back images, condition, seal or slab, and verification record            |
| Custody           | Intake, storage, owner, listing lock, and redemption eligibility                         |

This metadata remains attached to the same `inventoryId` through Vault,
Marketplace, and Redemption.

## Verification Matched To The Item

Professional grading is useful for eligible premium cards because a collector
can check a certificate in the grader's official database. It is not necessary
or economical for every low-price photocard.

Iruka therefore evaluates two tracks:

* **Accessible inventory** - exact item identification, authenticity review,
  front and back photography, condition record, tamper-evident storage, and
  custody reconciliation.
* **Premium inventory** - the same intake controls plus a matching,
  certificate-verifiable third-party graded slab.

Neither track allows a card to become `Vaulted` until physical intake,
verification, storage, ownership, and redemption records agree. See
[Grading and Verification](/product/grading-and-verification).

## Expansion Logic

Iruka does not expand by placing unrelated products in the same catalog. It
reuses the same physical collectible infrastructure while adding
category-specific identity and verification rules.

1. **K-pop photocards** - prove sourcing, verification, Vault, Marketplace,
   and Redemption for the initial category.
2. **Trot photocards** - add officially issued inventory after supply and
   identity controls pass.
3. **Cheerleader photocards** - add team, season, event, and subject metadata
   with documented supply.
4. **Sports collectibles** - add player, team, season, set, and
   category-specific grading evidence.

New artwork or branded releases remain a separate licensed-IP track and require
rights-holder approval. See [Roadmap](/roadmap) and
[IP and Listing Policy](/policies/ip-and-listing-policy).

## What Iruka Must Prove

The category thesis becomes a commercial product only after Iruka can publish
operating evidence for:

* Genuine physical inventory sourcing and item-level identity
* Authentication, grading acceptance, and custody reconciliation
* Pack inventory, odds, and completed-sale-based value methodology
* Ownership, Marketplace settlement, and listing locks
* Redemption, shipping, support, and regional policies
