It is quite a popular item here as most of the office workers eat out in Singapore. Many food choices like the affordable food centre (no aircon) and the slightly more expensive food court (aircon!).
Instead of taking the handbag, likely making the impression that you are not returning to office after lunch, most of us have a smaller bag or a pouch.
Just big enough to throw in the wallet and the handphone.
This is a customised order:
Thin canvas yellow printed external fabric with strong quilting cotton mushroom and bee print internal fabric.
Did they contrast or did they complement? In any case, the new owner loves it!

Very nice and practical. Saves carrying a big handbag around when you just want lunch.
