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.

Spendy but delicious. Helps with your teeth, so I highly recommend it.
Flavor Name: Watermelon, Size: 150 Count (Pack of 1)
Flavor is excellent, really tastes like watermelon. I wind up eating about four at a time, so it doesn't go real far, but I like it. I'll keep buying it because I love the taste. It's good for your teeth because of the xlitol. BUT don't let your dog find it. It can kill a dog, the xylitol. So keep it high up where your dog can't get to and wrap it before putting it in the basket so your dog can't get to it. No sugar, so safe for diabetics! High quality, nice packaging. Highly recommended, just keep your dog safe. If you take your dog in the car, don't take this in the car.
