Custom Thermos Flask

304, 316 and ceramic-lined

Most of the range is 304 stainless steel, the food-grade standard, fine for water, coffee and tea. A few use 316, which resists corrosion better against drinks like citrus water. Ceramic-coated flasks add a glazed inner wall, so nothing carries over from morning coffee to afternoon tea. The tea infusers pair a glass body with a steel filter basket, the only option here where you see the leaves brew.

Engraving lasts, printing carries colour

Laser engraving burns the mark into the steel, so it will not scratch off in a bag, but it comes out in the colour of the metal underneath. Colour printing gives the full artwork and matched brand colours, at the cost of a surface layer that wears at the edges over years of use. Dark and army green bodies engrave with most contrast. A full-colour logo reads best on the white and off-white flasks.

Worth knowing about metal bottles

Which size do most orders land on?
500ml, by a wide margin, with 400ml and 600ml next. It holds a full drink without being too tall for a desk drawer.

Does one flask handle hot and cold?
Yes. Vacuum insulation works in both directions, so the same flask keeps coffee hot and iced water cold.

What if we only need a handful?
One piece is a full order, and the unit price is the same at any quantity. Five for a farewell gift are as welcome as five hundred for an event.
