The straight-sided flask is the format most people already own and replace — slim enough for a bag’s side pocket, simple enough to look right on any desk. This version is built in 304 stainless steel and comes in four sizes from 350ml to 1000ml, so one specification covers a light commuter and someone who fills up once for the whole day. Printed with your logo, it becomes a daily-use item rather than a drawer item.

Why Choose the Straight Thermos Flask?

Four sizes, one order: 350ml suits a coffee run, 1000ml covers a full shift — you can issue different sizes across departments without changing the design
304 throughout: A single stainless grade rather than a mixed build, and the grade recipients expect for anything they drink from daily
The shape people actually carry: No handle to catch on a bag, no taper to work around — it slides into the side pocket where a bottle is meant to live
Hot and cold in one item: Coffee on an early shift, cold water through the afternoon, which a plastic bottle cannot manage
Replaces a daily disposable: One flask per desk removes a visible stream of takeaway cups and bottled drinks

Create a Staff Welfare Set?

A flask anchors a welfare or welcome pack because it is the piece recipients notice first. Pair it with a diatomite coaster for the desk it lands on, or with a canvas lunch tote bag so drink and meal travel together. For onboarding, an A5 PU leather notebook and an engraved executive pen alongside it make a complete arrival set — a coordinated group of corporate gifts rather than separate items. Present any combination in a custom gift box or a kraft paper bag.

Stainless steel takes both printing and laser engraving; engraving gives a permanent mark, while printing reproduces multi-colour artwork more faithfully. Our team can advise on which suits your logo before production.
