The whiskey stone is one of those "why didn't we think of that before" products! If you like your liquor cold, but you don't want to dilute it with melting ice - these are perfect. Won't impart any flavour to your precious drink, either. Six stones - simply keep in the freezer. Presented in the iconic and very trendy Mason Jar. From Brooklyn New York. Fantastic gift for any spirit-loving friend. Cheers!
