Not sublimatable
The Maars trap: one name, two coatings
The Maars Skinny Steel 20oz is powder coated and takes engraving only, with roughly a 3 x 3 in laser window. It shares its silhouette with Maars' own sublimation-coated line, which is exactly how the wrong one gets bought.
Why it will not work
Why the coating says no
Maars sells both sublimation blanks and powder-coated drinkware, in the same shapes, under the same brand. The rule that saves your money: read the SKU line, not the brand. "Maars Maker" polymer-coated SKUs take sublimation; "Skinny Steel" powder-coated colourways do not.
What the listings do not tell you
One more honesty note: Maars' own template library blocks automated reading, so this library holds no official Maars wrap dimensions. What is recorded for the Skinny Steel is its physical size, 8.25 in tall by 2.75 in diameter, which is useful for checking that a generic 20oz skinny wrap will drape its sublimatable sibling.

Can you sublimate a Maars tumbler?
Only the polymer-coated Maars Maker SKUs. The powder-coated colourways, like the Skinny Steel 20oz, take laser engraving only, and the two lines share the same shapes, so check the SKU line before buying.
What size is a Maars 20oz skinny wrap?
Maars publishes no wrap dimensions we can read, so this library does not state one. The physical body is 8.25 in tall by 2.75 in in diameter; the corroborated generic 20oz straight skinny wrap of 9.3 x 8.2 in is the sensible starting point, measured against your own cup.
