I got a great gift for my husband who does home tending as a hobby these days! If you just pour water into the ice cube tray without carving and freeze it slowly, you can get clear and pretty ice without bubbles😁 The same whiskey looks more luxurious with Jewel Ice🫢 It's easy to freeze, easy to separate, and thanks to the ice that melts slowly, you can enjoy the original taste of whiskey for a long time🥂
