Chaos Packs each contain 4 music NFTs created by Chaos, the headless band.
After minting your Chaos Pack, you can choose to keep your pack closed or open your pack. You can open your Chaos Pack by navigating to the Inventory tab.  Opening a Chaos Pack requires an additional on-chain transaction. This means that opening a pack will cost a gas fee.   Please read through the FAQs on the about page before minting a Chaos Pack.
