The Roundsky tumbler listing, bullet by bullet

Five bullets: splash-proof lids and stainless straws with cleaning brushes; double-walled vacuum insulation, hot for three hours and cold for nine, without condensation; a sublimation coating; a fully straight, not tapered body for full-wrap printing in a tumbler press or oven, plus straws wide enough for smoothies; and gift packaging.

Roundsky is straight

Not tapered, said twice. A tapered tumbler needs its design distorted to wrap evenly; a straight one takes a plain rectangle. The fourth bullet repeats the point for that reason.

What Roundsky does not give

No temperature, no time and no printable height. The mug press reviews on this site describe mug ranges; this listing names no press to check against.

Availability

At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 25 € to 32 €.

It is sold in the British Amazon store as well, in its own currency, which the euro figures above leave out on purpose.

The American Amazon store returned no entry, so the buy button there opens a search rather than a missing page.

Every figure here is Keepa’s reading on the date this page was last updated. Stock and prices can change at any time.
