Is your father a whiskey lover? Whiskey Stones by Teroforma may be the perfect gift for dad. These stones are great for enjoying a dram (1.25 ounce shot) of whiskey. Connoisseurs suggest that whiskey is best served neat (without ice). Freezing these stones adds the cold without diluting your drink. Just don't mistakenly swallow one. Yikes!
Available at RCKNDY, purchase the Whisky Stones for $20 for 9 stones or the Whisk(e)y Lover set, which includes 6 stones and 2 Avva tumblers for $60.
