We use all natural flavors in our 49 flavors of chips. Grom sweet like jolly rancher watermelon to OMG thats HOT. We leave the skins on and cook at a much lower temp to perserve 92% of the vitamins in the skin. We bag the chips in a clear celo bag so you can see the chips and see there is no oil on them and also see that you are getting a FULL bag of chips not air.
