Nooooo The medium sized bag I buy is less than that.
Maybe it's a small medium. I don't know.
I've always wanted to weigh my boobs though. But I'd feel a bit wierd just flopping them out onto the scales I bake cakes with.
oh in that case then no problemo - I can easily fit a half kilo bag in my hand and still give it a squeeze.
it'd be weirder if you were to try and weigh them in a chemist or something...
