Assorted Flavor Cartridge Pack of 4 – Zero Sugar Hydration Cartridge– Water Flavor Drops for Reusable Bottles – Long-Lasting, Customizable Taste – Healthy Hydration Boost – Sugar-Free, Calorie-Free. Received random flavor cartridges for the cirkul drink system. I love that they are all sugar free. All flavors taste great. Some have electrolytes for hydration and some have added caffeine for energy, some are just flavored. Decent price for replacement cartridges.

At the time of ordering, I know that I was going to get four randomly selected assorted flavors. The flavors I received are strawberry kiwi, mixed berry, white, cherry, and strawberry watermelon. One of the cartridges contains caffeine. They are easy to use and the taste are great.
