1981 Janice Portable/Disposable Ice Cube Tray Vintage Lot of 4 Deadstock

This is a lot of four portable and disposable ice cube trays made in Denmark by Janice. The packages are deadstock and still sealed, so I can only guess by looking at the illustrations that the product is like a plastic bag with 18 sections that you fill with water and freeze and...voila! Ice Cubes! Each package comes complete with cocktail recipes on the back, including the 'One Exciting Night'! A 'MUST' for that fancy day at the beach you have planned!
