After the untimely demise of London Mug Mark II M looked and found the name of who makes the mug. An easy search on the internet found a place selling the exact mug. About £20 later I ordered the replacement. I didn’t even have to go to Heathrow for this one like I did for the Mark II. The mug arrived right before our holiday (in February). This post is late getting published.
Hopefully Mark III has a longer shelf life than Mark II at 4 years or Mark I at under 2. If we are aging these thinks with a half life that means Mark III could last 8 years!
