About This Design

Technically, it's always full coffee mug

A glass is depicted half-filled with water and half with air, accompanied by the text "Technically, it's Always Full." The illustration plays with the concept of a "half-full" versus "half-empty" perception. A hand-drawn illustration " Technically, it's always full "depicts a glass of water with the chemical formula H₂O written inside. The glass is half-filled with blue liquid, and the text 'Technically, it's Always Full' is written above and below the glass. The image uses a simple, cartoonish style with black outlines and a white background.

Classic Mug, 325 ml
I have ordered from zazzle before and it was perfect. This time the mug has arrived in great time but the mug has rubbed on the box and has affected the image, I was hoping to get in touch with the creator but can’t seem to find a way of contacting them. We would love another sent out maybe wrapped in bubble wrap to protect the image. Would love to hear back from the creator. Kind regards, Lisa.
