When will there be items back in it?

The crystal shop is not like other shops because items get added to it kind of randomly, and it's up to certain staff members (like or ) to decide what items they want to put in there and when.

So there's really no way to tell for sure when new stuff will be in there, but they always do a news post when something is brought back.

thank you!

No problem! They do tend to put things in there somewhat often though, like about once a month usually.
