Cubic Cool Jazz Ice Guitars. It’s time to kick back and chill and here’s a cool way to do it! Drop one of these groovy guitars into your drink, and give it a stir. Cool Jazz is just a thing for jazzing up your favourite beverage.What a great piece of kit for Rock & Rollers! Simply fill the silicone tray with water (or something stronger!) put the guitars into the liquid and then just pop into the freezer. Great way to keep drinks cool and you can also make small Ice Pops with them.
