A pack of four bottle chillers that can be kept in the freezer, taking up very little space as they are a slender 14mm diameter and only 12cm long. When you need to cool down a bottled beverage quickly, you can simply drop straight into the bottle for a quick chill. Great for home use, and a great idea for camping or picnicking, rather than filling up your cool boxes with bulky bottles, you can freeze these and put in the cool box. Unlike ice, these won't dilute your drinks, and they will fit into the slim neck of most bottles. They are made from food safe hdpe, filled with distilled water, and freeze in just a couple of hours.
