Your morning tea, still hot at lunchtime
Stop reheating a cooled cup at your desk. This slim 500ml steel flask holds drinks hot or cold for 12 hours and fits easily into a commute bag.
Built to hold heat from first pour to lunch

Heat that lasts until lunch
Double-wall vacuum insulation and a 316L stainless steel body keep tea or coffee hot for 12 hours. The same walls keep cold drinks cold, so water at lunch is still cold. Pour once in the morning and the cup is still worth drinking at 1pm.

A slim body that fits your bag
500ml in a slim cylinder slides into a commute bag, a side pocket or a desk drawer without taking over the space. You get a full cup in a shape you will actually carry every day.

Mirror-polished inside, easy to rinse
The inner wall is polished to a mirror finish, so there is no matte texture for residue to cling to. A quick rinse with hot water clears it, and you can see at a glance when it is clean.
Your first pour, step by step
- 1Rinse with hot water
Fill the flask with hot water and swirl it for about a minute. Pour it out. A warm interior keeps the first pour from cooling down early.
- 2Fill with your drink
Pour in fresh tea or coffee. Let it cool for a few minutes before you seal the lid, so trapped steam does not build pressure inside.
- 3Seal the lid firmly
Screw the white lid down until it stops and confirm the steel seal ring sits flat. Open it slowly when you are ready to drink.
- 4Rinse and air dry
Empty the flask after use, rinse it and leave the lid off to dry. Residue left overnight is what causes stale smells.
A smooth inside that rinses in seconds
- Rinse after every use
A mirror-polished interior has no matte texture to hold residue, so a quick rinse is usually enough.
- Use a soft sponge
Keep abrasive pads and steel wool away from the inner wall to protect the mirror finish.
- Dry with the lid off
Leaving the lid open lets air reach the inside and prevents stale smells.

Questions and answers
The inside is a polished 316L steel finish, and it is the smoothest surface in the flask. Rinse with hot water after each use and use a soft sponge. Skip steel wool and abrasive powders, since any heavy scrubbing will dull a mirror finish over time.
500ml covers a morning cup and a refill for most people. It is the slim option, the one that fits a bag where bigger flasks do not. If you drink more than that across a day, a larger flask suits you better.
The lid screws down onto a steel seal ring. Turn it until it stops, check that the ring sits flat, and then pack the flask upright. Give the lid a quick check after the first few uses, since a seal that is not fully seated is the usual cause of drips.
You are paying for 316L stainless steel, a double-wall vacuum body and a mirror-polished interior that rinses clean. Cheap cups lose heat fast. If the flask replaces one takeaway coffee a week, it pays for itself within a few months of daily use.
Yes. The same double-wall construction holds drinks hot or cold for up to 12 hours, so iced tea or cold water stays cold through a long commute or a day at the desk.
