Specification

Built like
an instrument.

A vacuum flask is only as good as its seal and its steel. This one uses 304 stainless on the wall that touches your drink, and a lid that measures rather than guesses.

Questions

Before you buy.

How do I replace the battery?

Unscrew the display cap and open the compartment underneath. It takes a standard coin cell — swap it and screw the cap back on. No tools, no cable.

Can it go in the dishwasher?

No. Hand wash the body and filter. The display cap must never be submerged or machine washed — wipe it with a damp cloth.

Does the display show Fahrenheit?

Celsius only. For reference, 60°C is about 140°F and 95°C is about 203°F.

When will it arrive?

Dispatched in 1–2 business days, delivered in roughly 12–20. It ships direct from our manufacturing partner, which is what keeps the price where it is.

What if I don’t get on with it?

Send it back within 30 days for a full refund. Used is fine. Your statutory 14-day right of withdrawal applies on top.
