- Listing details are contradictory or unconfirmed: the title offers 0.5L, 0.75L and 1.1L, the manufacturer description specifies 1.1 L, and the details field gives a capacity of 1.05 kg, which is a mass unit rather than a volume. Hot retention is stated as 18 hours, while cold retention appears as both 24 hours and 25 hours. Confirm the selected bottle size and applicable cold-retention claim before buying. The description also calls the body 18/8 stainless steel while the materials field says “Other”.

## Frequently asked questions

### What is the bottle’s capacity?
The listing is inconsistent. It gives 1.1 L in the manufacturer description, 1.05 kg in a capacity field, and multiple sizes in the title. Confirm the selected variant’s volume before ordering.
### How long does it keep drinks hot or cold?
The listing states hot for up to 18 hours. Cold retention is given as both 24 and 25 hours, so treat the cold duration as unconfirmed.
### Can the cap be used as a cup?
Yes. The listing describes the top as usable as a coffee or tea cup.
### Is it dishwasher safe?
No. The care details say hand wash only.
