Wanted: Deliveroo/similar food delivery style backpack

Looking for a food delivery style backpack. Wanted due to the internal dimensions of 36cm x 36cm x 43cm.

Turns out this is perfect for the boxes I use to transport warhammer.

Can collect within reasonable distance of E17 or pay postage.

I've got one of the large Stuart thermal rolltop bags that's not seeing any use, internal dimensions may come up slightly larger than that but certainly not by much

EDIT: Just checked and it's effectively 40cm x 40cm x 40cm
