I chose these handwarmers thinking they would be just enough, they are about the size of your palm and do last quite a while, but the little Winnie the Pooh characters rub off just by holding them, and then completely disappear when you reheat them. Also, 3 out of my 4 actually worked. One of them didn't even have a metal chip inside!! (that same one burst in my pocket later) I was particularly upset when I didn't get all 4 characters. I got 2 Winnie the Poohs, a piglet and a tigger but not an eyore!! Who happens to be my favourite.
They are terrible value for money although they are good handwarmers.
