About this design
For the engineer who can't look at anything without thinking about how it was built — and how they'd do it differently

I May Start Talking About Engineering at Any Time Mug is for the engineer who considers their discipline the one that actually builds the world.
Perfect for
- Engineers of every discipline
- A brilliant gift from colleagues or people who've benefited from their practical knowledge
- Birthday or Christmas for the person who considers a well-designed object to be a thing of beauty
- Anyone who spots a structural problem in a TV programme and mentions it out loud
