I saw a green, vintage Tupperware one of these in an op shop a while ago, but at $10 I thought that hardly constituted a bargain. Then I saw it at a different op shop for $3, but it was too late! I'd already snapped up this pre-loved IKEA one for $3! Oh well - the important thing is that now when I grate cheese or carrot it doesn't fly all over the place. And it converts to a storage container just like the lovely Tupperware one did.
