# Inventory

#### Ownership

All digital cards are owned by users as Non-fungible Tokens (NFTs) and are backed 1-to-1 by physical cards.

#### Graded Cards

Graded cards are authenticated cards by grading and authentication services. Gacha only offers PSA graded cards at the moment. We intend to expand to TAG, CGC and BCG in the future.

Some PSA-graded cards in the inventory do not show PSA ID under Gacha Inventory page because their card scans are older and not available. Rest assured that they have individual IDs that are verifiable.

#### Mystery Card

Mystery card is a digital card minted when inventory at a certain price point is out of stock. Mystery cards can either be sold back to the platform or redeemed for a card of the same value later. The redemption feature will be available in a later update.

#### Storage

Card inventory is replenished and maintained on an as-is basis to make sure users have the best cards. 

Each digital card is backed by a physical card, authenticated and stored securely in reputable vaults (PSA & Dyli).

#### Insurance

Each physical card in our vaults is insured at full market value by a third party insurance provider during storage and when shipping to the users. This ensures that users will receive the full value of the products purchased.
