There’s an infinite amount of whatever is in a container as long as nobody (Including you) is looking inside of it

This only works for you and what you’re interacting with

Whatever was put into the container is essentially cloned in the condition it was in when put inside of the container

The container’s weight is only affected by what was put into it

examples would be putting a single battery in a small box and grabbing as many as you want from the box, flipping a bottle upside down would constantly have it spilling, unlimited bottom of the bag fries

You can put more than one thing into the container but it’ll be harder to take what you want out of it
