John B Java Tumbler 10oz

Good coffee should not be allowed to go cold.

If you are drinking specialty-grade, small-batch roasted coffee, letting a mug of it sit and turn to room temperature beside a keyboard is a genuine waste. A vacuum wall is the fix — heat cannot cross a vacuum, so the last mouthful is close to the first.

Ten ounces is the size that actually gets finished: enough for a proper cup, small enough to sit on a desk, a console or a workbench without taking over the surface.

Sublimation, not a sticker.

The artwork is sublimated into the surface coating rather than printed on top of it, which is why it does not peel at the edges or fade to grey after a month in the cupboard. Hand washing still gives the longest life — dishwasher detergent is abrasive, and heat cycles are hard on any printed drinkware.

Twelve years of late nights.

Since 2014, John B. Wells has put out more than 2,800 episodes of Caravan to Midnight and over 500 Saturday nights of Ark Midnight — reaching millions of listeners across terrestrial radio, digital satellite, live stream and podcast.

Everything in this store exists for the people who made that possible. Buying it puts something in your hand; it also keeps the microphone on.

“Take no part in the unfruitful works of darkness, but instead expose them.”
