You should be able to send them from your Metamask wallet by "manually adding" them, as per Metamask's own guides.

The "contract address" for Skyweaver Conquest Tickets is 0x631998e91476da5b870d741192fc5cbc55f5a52e, and the "token id" is 16646145

Same thing would be for cards, you will need to manually add each card with its "token id".

Alternatively, you may also use Polygon's interface to send your items on Metamask back to Skyweaver.

We recommend that you try 1 item first to make sure it works and avoid any errors. If you need help, please free to reach out and we'll be happy to help!
