Hey, there! I received my three-year Loyalty Box a couple of weeks ago, and am still deciding what I'd like to use it for. But I'm worried that in the time it takes for me to make a decision, it will be stolen by Lizard Minions or be taken away by some other random event. I would lock the item or put it in my vault, but I can't do anything but open it!
Anyone know how I can be helped, or if I just need to stop being so fickle? CX I'd appreciate the help.
You should file a ticket because Loyalty Boxes and Totems can be locked.

You're able to lock it in your inventory (from the inventory screen, not the options), but they disabled the Rotten Rogue event that steals items so it'll be fine even unlocked.
there is no reason to file a Ticket here, nothing is broken or not working like it should.
A few weeks ago the only stealing NPC, The Rotten Rogue. was reformed. It is no longer possible for items to be stolen.
Lizard Minions happen to things that you stumble across as a Random Event. The "not interested in your items" event is a non-issue, because the item isn't quite yours yet (if there ever was one, which in this instance, there's not) it's on the ground or falling out of the sky or something.
The only thing that can destroy your Box is an Ultimate Zap. Lock your box, if you've got the slots left in your Inventory. If you don't have any locks remaining and you are zapping your pets with this, you should stop until you decide.

oh aha! Nobody can do anything with this item but open it. The resulting totem can only be used.
There was much debate about Loyalty Boxes, Subeta didn't used to do this. People were saying that they'd be sold on the open market or given away or stashed and then opened all at once.
Right. She should be able to lock it if she does have an open slot though. Hopefully the solution will be something simple like unlocking another item to free a slot. :)

Locked it! I just didn't realise that you just had to click on the lock icon! I was trying to do it through the items options page. Thank you so much for helping, everyone! I appreciate it. c:
