# 📦 Booster Packs

Booster packs are limited to a certain maximum supply. Currently, the plan is to have a maximum supply of 100,000 packs. While this may seem like a large number, each pack will contain only a single monster. Given that most collectors would likely want to own two or more monsters, this number becomes more reasonable.

Packs can be minted from a linear bonding curve. The initial price per pack will be set at 1 PMON and will increase by 0.001 PMON with every pack minted. For instance, the 500th pack can be minted for approximately 1.5 PMON (fees are explained below). If you choose not to open a pack but instead wish to sell it, you can return it to the bonding curve and claim PMON. For example, if you mint the first pack for 1 PMON and then 500 people also mint packs, you can swap your pack for 1.5 PMON. Conversely, if you mint pack number 1000 for 2 PMON and then 500 packs are swapped back, you can only swap your pack for 1.5 PMON. As mentioned in the disclaimer, packs should not be viewed as an investment.

For every swap to or from the bonding curve, an additional fee of 10% will be charged by the smart contract. All of this fee shall be used for battle reward pools. More information on this will be provided soon.

Should all 100,000 packs be minted, they will only be available for purchase on secondary markets. Details about the opening will be announced shortly.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://battle-docs.polychainmonsters.com/monsters/booster-packs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
