Here's the product description and meta info for the Old Fashioned refill:
Old Fashioned Infusion Flavor Pack — Refill for Your Rokz Bottle
Ready for another round? This refill pack gives your Rokz Old Fashioned Infusion Bottle a fresh start. Add the ingredients, pour in a pint of whiskey, steep for just 1–2 days, and you're back to pouring a richer, fruit-and-spice-forward Old Fashioned than anything you'd get from a bar.
Same great blend, same great results: Dried apricots, dried cherries, lemon peel, orange peel, clove, cardamom, cinnamon, and cane sugar — warm, layered, and worth repeating.
How to use your refill:
Try "Simply Maple": 2 oz of your Old Fashioned infused bourbon, 1.5 tablespoons of maple syrup, an orange wedge, and a cherry in a lowball glass. Muddle the fruit, add large ice cubes, stir until well combined, and finish with a squeeze of orange peel.
