How long will the rare prism shop be open on NA?

I assume it will stay open but might not always have something to sell. More mystic codes and CE's are supposed to become available from the rare shop, and I'm saving my rare prisms for the return of Mona Lisa

Should stay open forever, the products inside of it are another matter. There'a s crystal lore there right now but it'll be gone in a few weeks.

The shop itself will always be there, the items have expiration dates written on them.
