Tired of your drink getting watered down with melted ice? Having a party and want each guests glass to be tagged so they keep using the same glass? Want a reuseable ice cube which doesn't soak the bottom of your freezer tray in a layer of ice over time. Our handmade glass ice cubes / whisky coolers are just what you're looking for! They come with a special freezer bag, and as they are handmade with the highest quality borosilicate glass they are safe to be frozen or heated up. Just give them a quick rinse under the tap after use and they are ready to be popped back into the freezer ready for next time. Each cube is over 30mm in width which means they are made to the european standard and cannot be swallowed. A set of six come in black, white, blue, green, red and yellow. The other sets come in a selection of the six set colours.
