Where can I buy like an ice cube try thing for storing breastmilk?

[tutu100]

I have seen a thing that looked like an ice cube try, but it had a lid and each section held an oz of milk. Does anyone know where you can get these as I have forgotten where I saw it.

I need something like this as don't want to freeze whole feeds in bags or via cups.

Can't you just use a normal ice-cube tray??

is it like this?

I just used an ordinary one but with oval shaped cubes that slid out of the tray easily for bagging once frozen. Whatever you do, if you have a dishwasher, make sure it's one that will go through it without twisting or you'll be cursing it forever!

They are sort of like that Seona, but they were all one part with just the one lid. Is it ok to use a normal ice cube tray? Will an oz fit in each cube. Please excuse my dimwittedness, but the 5 week old baby has completly lost my commmon sense.

here?
