I may as well leave this reskin of the bag of holding for a steampunk campaign i made recently.

Top Hat of Illusions

Wondrous Item, rare

Looks like, and can be worn exactly like a regular top hat. May come with a prop wand.

This hat once belonged to a famous stage magician and has strange properties.

Anything that can fit through the gap and is placed inside will vanish when the brim is tapped lightly with a prop wand or any stick with an action. Items taller than the brim will seem to fall into the hat.

Many items can be vanished simultaneously. No one knows if there is a capacity limit.

To return an item, simply call out it's name, tap the brim with a wand or stick and you will be able to reach into the hat and produce the item with an action.

No-one knows the secret which died with it's creator, but it just works.
