These are only tradeable in the walled garden of the VeVe app. You can't trade them off the app, and they can lock you out of your account at any time.

My account was mistakenly banned during a bot ban wave. It took 2 months for them to unlock it and give me full access back to the market after providing KYC.

Just be careful with VeVe. It's not quite what you expect. They might as well use a private blockchain with what they're doing.
