Hello kitty bento box

I had seen this Hello Kitty “sandwhich” box in tesco a few times but I didn’t want to pay £4 for a box the same dimensions as one I paid £1 for just because it had kitty’s face on it. But then today it had been reduced to £2.34 and I knew if I didn’t buy it I would moan about it for ages.
It has a 600ml capacity.
And as its marketed as a sandwich box it makes me a little sad that kids are missing out on what could be inside if their parents packed a healthy diverse bento lunch.
