I personally thought they looked like most pastels, and look great. I mean granted I'm sure there are some out there that are more unique, but still nice in my opinion with an average pastel look. If those were mine, and you offered me 50 bucks I'd tell you to take a walk lol. I would say 75 bucks for a male, and 125 for a female is fair.
All pastels brown out with age, and none really keep that crazy yellow complexion. Its still yellow, but kinda has a brownish looks to it as well. The sides of the pastel should remain very yellow though. Most pastels I've seen all look the same for the most part. Again, your going to get the odd one, but these TO ME exude more then "pet quality." Just my 2 cents.
** I would choose the one on the right being that hes more yellow **
Figured I would show my pastel just to show you how they brown out. Mine looked a lot like the one on the right in terms of color. Heres how he turned out
Also...In case your looking to breed here are his offspring.
If you like the snake buy it simple as that. Mine was "pet quality" but made some beautiful babies. So just goes to show how much that matters.
