Simple to fill, easy to load into your freezer and to decant individual cubes without having to touch the ice. Because it is sealed, it stops the ice from absorbing the odours and crumbs of other foods in your freezer. Fill up the polar bear until water escapes from his back. Put him back on his feet and into the freezer. Once frozen, bang him on his back (Ouch!) and empty the ice cubes into your whisky!
