File dividers that fit storage boxes (see reference)

[daysfilledwithdappledlight]

Have seen this from someone in the US www.instagram.com/reel/DFtb4Cny0LS/?igsh=YXhldzBwcHZqZ3F5 and would love to re-create but can't find any file dividers that pair with large boxes like these!

Has anyone done something similar and can share where they got them from?!

Really useful storage boxes have some that fit standard A4 or foolscap hanging files

Scroll down past buy button to the 'spec' info for which sizes fit which, but you can buy the boxes just about anywhere.
