Soft & Moist
Size: 9 Ounce (Pack of 2), Size: 9 Ounce (Pack of 2)
Tried this from a Sam’s Club combo pack of the jerky and like but size nugget deals. LOVED the jerky enough to figure out if I can order just big regular size bags of the jerky. And you can. And I did. The quality of the big bag of jerky is as good, wonderful, soft, moist, as the little small snack size bags I tried to Sam’s Club. If you like soft jerky that is not super chewy, and that does not get stuck in your teeth unless you are really trying, I would definitely recommend this
