Do you have your own mug for the office? I’m sure I speak for most of us that I hate it when other people use my mug without permission. Even worse is when they don’t wash it and left it overnight on their desk, now I had to use the communal office mugs.

Well this new mug design is perfect for people like us (that is normal) - it has a hole that can only be plugged by a special “key”.
