Using the silicone mould make a solid 5cm ball of ice by simply filling the mould and freezing. You can also fill with fruit for great effect. Once frozen, release from the mould and place in the Rocks glass. Pour in your favourite tipple and roll the ball of ice around the “rock” in the centre of the glass to not only chill your drink but also to release the flavour and scent. Packed in a smart gift tube.
