Looking for a tiny rucksack-style bag

[CinnabarRed]

Please help!

I want a really small bag - the kind of size to fit a mobile phone and my keys, and maybe a lipstick but no more (so basically clutch sized). But I want it as a rucksack style.

Does such a thing even exist?

Thank you.

TK Max’s has some like this. I got one for my dd who was nine at the time and it’s very small.

This comes in a number of colours veratuccioriginals.co.uk/collections/leather-bags/products/kitty-miniature-backpack?variant=33084021211273 and is a bargain at £20

Thank you - excellent suggestions!
