# 5.7 How to Use KOZUCHI

KOZUCHI is an item that raises the payment amount cap used to calculate BIND rewards.

When you use KOZUCHI for a Check-in, the eligible payment amount for that mari ball's BIND increases from the usual USD 100 to **up to USD 150**.

KOZUCHI is available only to users with Trust Rank S or higher. BIND limits, including daily and monthly limits, take precedence. KOZUCHI does not let you exceed those limits or your remaining allowance.

#### What KOZUCHI does

| Item                        | Details                                                          |
| --------------------------- | ---------------------------------------------------------------- |
| Eligible payment amount cap | USD 100 → USD 150                                                |
| Eligible rewards            | Econ or EVT, subject to their respective earning conditions      |
| Experience points (EXP)     | KOZUCHI does not increase EXP                                    |
| Lifespan consumption        | If more EVT is earned, the additional EVT also consumes lifespan |

The higher cap applies to the BIND linked to the Check-in that used KOZUCHI. It does not make every BIND reward 1.5× larger.

For reward conditions and calculations, see [Payment Ranges](/rewards/payment-ranges.md) and [Reward Formula](/rewards/formula.md).

#### Use KOZUCHI when checking in

The KOZUCHI icon and balance appear on the check-in confirmation screen only if your Trust Rank is S or higher, you have KOZUCHI, and you meet the usage requirements. If your Trust Rank is below S, or if the check-in earns only EXP, the KOZUCHI option is not shown and KOZUCHI is not consumed.

1. Select the store you visited and open the check-in confirmation screen.
2. Tap “Use KOZUCHI.”
3. Make sure the icon turns green and check the MANEKINEKO you want to use, then confirm your check-in.

Mari-balls earned using KOZUCHI will have a special icon.

You can also check in without using KOZUCHI.

#### Find mari balls that used KOZUCHI

A mari ball from a Check-in that used KOZUCHI displays a KOZUCHI icon.

In the list of unopened mari balls, check the store, date, and KOZUCHI icon, then BIND the matching payment data.

#### Previously distributed KOZUCHI

KOZUCHI already distributed through SyFu Card monthly item drops cannot be transferred. You cannot list these items on the SyFu Marketplace or send them to an external wallet.

#### Before using KOZUCHI

* Deleting a Check-in that used KOZUCHI does not return the item.
* Using KOZUCHI does not increase the EXP you earn.
* If more EVT is earned, more lifespan is consumed. See [Lifespan, HP, and Durability](/manekineko/manekineko-nft-lifespan-hp-durability.md) for details.
