Yup, looks kind of thin. Not "thin" for any snake...but for a young Ball Python. Yup. They should at least have a pleasant plump-ness at this age.
Which bears the question, why so thin ? Esp. for a rather nice morph ? A female, too, which most people would take care to feed and grow well (even if not power feeding).
And then, who has such a morph, female, over a year old and wants to get rid of it rather cheap ??
Maybe its just me, but I have learned that this is just about always true >> if it sounds to good to be true, it probably is.
And this is not a object, its a animal. One that could potentially endanger the rest of your collection.
I would ask a LOT more questions first. About the feeding schedule, the weight, mites, any issues...etc. If the seller gets offended or is not willing to answer everything gladly, well, you have your answer then.
IF you do decide to go for it. Don't spend more then you can afford to loose. Absolute STRINGENT quarantine.
And good luck with whatever you decide
