Product Description 1. INNOVATIVE DESIGN: With this sphere ice ball maker, you can get 4 or 13 full ice balls at a time, which is much more innovative design than most of the similar ones that can only create one ice ball at a time. 2. SUPERIOR QUALITY: The bottom is made of BPA free hard plastic while the cover is rigid but flexible premium silicone material, these round ice ball molds are much more durable to use for years. 3. CHILLING AND INTENSIFYING FOR YOUR BOURBON: The most key point for better tasting whiskey is to stay chilled all the time without getting diluted. The large ice balls melt slowly to avoid dilution and can also make the drinking atmosphere more upscale when floating in the drinks. 4. EASY TO RELEASE AND CLEAN: The old fashioned ice cube mold made of flexible silicone allows you to release ice cubes easily. The smooth silicone surface makes it easy to clean. 5. Whether you're sipping some cold drinks by your private pool to protect yourself from the hot summer, or sitting by the fireplace with your dog, enjoying a cold bourbon or cocktail to relax after a busy day at work in the cold winter, this sphere-shaped ice ball mold is always the best choice for making ice for you.
