Hey Chad,
Have your friend send me an email about those snakes. I've seen a few full stripers on kingsnake. I think theres two right now. One full stripe salmon and 1 full stripe normal het for albino. From what the ad says it seems to be genetic. One of the litter had 4 full strip babies I believe. The full stripe het albino was going for 2000.
