you summon a chest in front of you for up to 2 hours, or until you use a bonus action to dismiss the chest. The key used for this summoning will allow the opening of this chest, In case you used an arcane focus, the safe is not locked. This chest can hold up to 500 pounds of equipment in a space of 12 cubic feet. Each time you summon this chest again, the equipment you previously placed in it will still be present.

If the chest is broken, forced or suffers significant damage, it opens and is destroyed, its contents scattered around the place where it was previously. Breathing creatures inside the bag can survive up to a number of minutes equal to 2 divided by the number of creatures (minimum 1 minute), after which time they begin to suffocate.
