Insulated thermoses and carafes, including vintage floral patterned tea thermoses with removable infusers at 1.5 litres, in 316 stainless steel.
Two details matter to a buyer here. The 316 grade stainless is a step above the 304 used across most of the category and resists corrosion from tea tannins and acidity, which is a genuine durability claim rather than marketing. The integrated infuser turns a vacuum flask into a tea specific product, which separates it from the generic thermos aisle.
Patterned finishes give the category gift appeal beyond pure function. Merchandise with french presses and stovetop kettles within the wider coffee and tea block.
