I'm actually happy with the M&S case, I'll put toiletries in it for travelling. It's useful to have a large one that can fit all the shampoo, suncream etc.
I agree I wouldn't display it anywhere but it will be handy.
I do have two older Liberty ones I've kept and will reuse those for kids advent calendars.
I do like the idea of a cake tin because I don't have one off those.
