Epic Floor Design, although I'm not sure what the idea is. if laid with clear or glass tiles to see the design would be different, but to put black tiles over doesn't make any sense. I wonder if you get a magnifying glass to view the floor.
This design is functionality. It added a small container in the bottle cap and you can put pills inside.Therefore when you drinking water,you will know that you need to take pills.But i think it can put other small items inside the small container.
