Can anyone find me plastic food storage boxes the right size for packs of cold meat?

[AMumInScotland]

I tend to buy biggish packs of ham or other cold meats - about 20cm by 16cm. I'd like to be able to pop the opeend pack in a plastic box in the fridge - I don't like leaving them open, and I'm trying not to use so many plastic bags.

But I just can't seem to find boxes that sort of size, but quite shallow. Or really tall flat ones I could post the pack into.

Can anyone point me in the direction of ones that sort of size and shape?

Asda do them. I take them out of the plastic and put the meat in the box.

Ooh thanks, I haven't looked in there - I'll have to pop in next time I get a chance, it's not very handy but I can make a trip!
