Wondrous item, rare

This canister can hold up to one Tiny creature or object. You can use your action to open or close the container. Once closed, the creature or object within is not exposed to the ravages of time, a creature within the canister does not need to sleep, drink, breathe, or eat, and anything within the canister ceases to age, rust, or otherwise decay. 

• The canister is immune to all damage. And can only be destroyed by a wish spell or similar magic.
