What Happens to Unspent Windborn Stamps in Aniimo has an important Season 1 answer: they are automatically converted into Credits when the current Part ends. Windborn Stamps are the Part One Season Stamp currency, so they are not intended to roll forward unchanged as the Part Two shopping currency.
If you are asking What Happens to Unspent Windborn Stamps in Aniimo because you are saving for a Stamp Shop reward, the deadline that matters is the end of the Part, not the normal Monday shop reset. Weekly stock refreshes every Monday, but your Windborn Stamp balance remains usable during Part One until the Part transition converts the leftovers.

| Timing | What happens |
|---|---|
| Monday 04:00 server time | Weekly Stamp Shop stock refreshes |

Do Windborn Stamps reset every Monday?
No. The Monday reset applies to weekly systems such as the Stamp Shop’s recurring purchase limits and the Stamp Rush period. It does not mean your entire wallet is wiped every Monday. This distinction is the most common source of confusion around What Happens to Unspent Windborn Stamps in Aniimo.
You can earn Stamps during the week, hold them through a Monday refresh and then spend them on the newly refreshed stock. The Part-end conversion is the point where you need to make a final decision about the remaining Windborn balance.
Should you spend Windborn Stamps before the Part ends?
If there is a limited reward you actually want, yes. What Happens to Unspent Windborn Stamps in Aniimo matters because Credits are widely obtainable through other activities, while several Stamp Shop rewards are tied specifically to seasonal spending thresholds or weekly limits. Letting Stamps convert automatically can therefore trade a rarer purchasing opportunity for a more common currency.
Check the seasonal tab before the deadline, especially if you are close to unlocking Sparkling Egg, Sparkling Cube, Flameplated Dragon Shield, Prismana Orb or Phenomena Crystal purchases. Remember that hitting a cumulative spend threshold unlocks the offer, but you still need enough Stamps left to pay the item’s purchase cost.
What should you buy before Windborn Stamps convert?
There is no single answer for every account, but the best way to use What Happens to Unspent Windborn Stamps in Aniimo as a planning question is to compare your balance with the rewards you cannot easily replace elsewhere. Weekly materials, Irisalis Petals and seasonal unlocks can all be more valuable than allowing the same currency to become Credits automatically.
Our Aniimo Stamp Shop guide lists the current Weekly stock and seasonal thresholds. If you are short of your target purchase, How to Get Windborn Stamps in Aniimo covers every current source, while Aniimo Stamp Rush explains the main weekly earning pool.
What happens to unused Stamp Rush allowance?
Do not confuse unspent currency with unused earning allowance. Current client-based documentation says unused Stamp Rush allowance can carry into a later week, while What Happens to Unspent Windborn Stamps in Aniimo is about the currency already sitting in your wallet at the end of the seasonal Part. Those are two different rules.
What Happens to Unspent Windborn Stamps in Aniimo should not be confused with over-cap earnings either. Likewise, excess Stamp earnings above the applicable weekly allowance can be handled differently from a wallet balance at Part end. Always read the counter attached to the activity you are claiming rather than applying one reset rule to every seasonal system.
When does Part One end?
Current Season 1 schedules place Departure with the Wind Part One through October 28, with Part Two beginning around the October 29 update transition. Use the in-game Season timer for the final countdown because maintenance can affect the exact moment the next Part becomes available in your region.

The practical answer to What Happens to Unspent Windborn Stamps in Aniimo is simple: spend them on the Part One rewards you genuinely want before the seasonal transition, because any balance left over is converted into Credits instead of becoming the next Part’s Stamp currency.
