Very small water bottle

[SpamIAm]

I'm after a little water bottle for my daughter's lunchbox. She has a larger bottle for water during the day so this would just be for a bit of squash or something with her lunch.

The smallest I've been able to find is the Sistema 330ml ones but ideally I'd like something more like 150-200ml. She's 4 so needs to be something she can do herself - she's fine with straws, twisty ones, sports caps etc but wouldn't be able to do a screw cap.

Has anyone seen anything that fits the bill?

Thanks!

Could she manage this?

What about bottles runners carry?

Try looking at running bottles - there's lots of little ones designed to slip into running belts.
e.g. runcompany.co.uk/products/flipbeltbottle?variant=19346454741061

Also flexible ones which would squeeze into a little space?

Thanks everyone! I didn't even think of searching beyond kids water bottles so the running ones is an excellent shout, I think I even have a couple somewhere.
