Unexpected treat!!
Flavor Name: Watermelon, Size: 150 Count (Pack of 1)
This gum tastes absolutely amazing. And doesn't leave that nasty gritty film on your teeth that you expect from most gums. It was a real unexpected treat.

Addictive, Clean Ingredient Gum That Feels Healthier
Flavor Name: Watermelon, Size: 50 Count (Pack of 1)
Very enjoyable flavor with clean, healthy ingredients. Feels like a healthier alternative to typical gum and is highly satisfying. Price is not bad for quantity. Makes my breath smell good and fresh.
