Stainless Steel Travel Mug "POLYOMINOES" Col Mint Chocolate

Jhane's Take on the “Travel” Mugs

(which I’m renaming, because words matter)

These are made by the same printer as the tumblers, using sublimation, so the printing quality is consistently high: rich color and clean application.

What’s different here is that these mugs aren’t true cylinders, which makes seamless wrapping tricky. The printer uses software that gradually adjusts the artwork so the edges meet without a visible seam. When it works, it’s impressive.

What surprised me is which designs survived this process.

Most of my flat-color geometric designs worked beautifully. The designs that failed were the ones with extremely complex, multi-million–color patterning. Even when the digital preview looked perfect, some of those patterns simply didn’t translate cleanly onto the tapered form in real life.

Because of that, every design has to be physically tested, which is frustrating but unavoidable. Anything that didn’t pass that test is gone.

The mug itself is stainless steel and vacuum insulated, and feels solid and well made.

The black plastic lid screws in securely, but this is not a true travel lid. The pull-back drinking tab does not lock tightly enough for a bag (Katsu confirmed this the hard way), so I’m changing the name. This is really a desk or table mug, not something I’d recommend tossing into a backpack.

I also wish there were a straw option. That’s outside my control, so I use a Klean Kanteen tumbler straw lid at my bedside — which works exactly the way I want it to.

Beautifully printed, technically clever, but with real constraints. Once those are understood, these mugs make sense.
