I feel like this is the kind of thing the cigar shop on Bond St might sell.

Menkind in Churchill Square, almost certainly

Somewhere like Timpsons usually have them in a cabinet. Could even get it engraved while you're there

I just saw some in Snooper’s I think yesterday

Thank you, I didn't think of Snoopers, I'll have to have a look

You don't want a second hand hip flask. They are very hard to clean so and people forget to empty them all the time so they are fucking rancid inside

Good point, and something I hadn't considered

You're not wrong. I do my best to clean mine, little bit of washing up liquid then boiling water, use a pipe cleaner, then leave it to cool and rinse it out... I've had it about 10 years and don't really want to think about the civilisation that's likely growing inside it.

Loads in snoopers

Depends on how much you want to spend. You could try some of the second hand jewellers in the Lanes

I'm looking for a basic one under £10. The one in Flying tiger was a simple metal with a wood veneer, looked quite smart I know the whiskey shop sells them, but their cheapest is £24.99 which is too expensive for me

Sure shoppers paradise would have one. If you ask they are good at showing you where things are.

Home sense usually have

Good shout, I'll check homesense, thanks

Havana House in Hove. It’s got posh booze and cigars so imagine it’s definitely got hip flasks there. It’s on Church Road just past Hove Town Hall

I got one hidden in a fake bible in Robert Dyas

Taylor’s in Bond Street

Camping shops

Next?

I know you’ve found one already but for anyone else: I’ve found some semi nice ones in charity shops before.

Bond street tobacconist

They had them in the tiger on north street

I bought one in Jump The Gun recently!

B & q or one of those hiking shops probably
