Set of 4 stainless steel ice cubes. Size: 2.5cm x 2.5cm x 2.5cm cube - Chill in the freezer and use in drinks instead of ice. - They don't melt, so they won't dilute the taste of your alcohol or juice. - Made of rust-resistant stainless steel. - I bought these as an alternative to ice, but they take time to cool items that are already at room temperature. They seem to be better at keeping things that are already cold, cold. Please read my profile before considering a purchase. Thank you.
