Faction Boon purchase question

[Aricks]

So from reading the Boon section of the Organized Play guide, do I have it correct that Boons purchased as well as obtained from Chronicle sheets can be maintained like an inventory, and slotted and used as needed on a per adventure basis?

Or, once a boon in slotted it remains there until you sell it or use it up (in the case of limited use boons).

From the rules reading I'm 90% sure it's the former but that 10% remaining prompting this post.

Thanks!

You own them forever (or until used, if they're limited), but can only select (slot) up to 5 per Adventure.
