Full or Empty / public toilet door

Full or Empty
Full or Empty

As we all know, public bathrooms have a high usage and embarrassing situations often happen. At times we find ourselves urgent in a stall with an empty toilet paper roll and it happens more than it ought to. To solve this issue, we have come up with a product where you can check how much toilet paper is left in the stalls from outside the door.
