Skinny neck

Hi. I am very new to the ball python world. I have a 4 month old spider ball python that I bought my daugter for Christmas. I"ve had him about 2 months...but he's been living with a friend who has had many many snakes and has taken very good care of him. So, I got him this morning to get ready for Christmas morning and noticed that his neck is very skinny, but his boby looks nice. Is this normal? Kinda looks like the skin is really wrinkly and falling off his body. He's at the end of a shed though, so didn't know if this was to be expected. Would appreciate any help or insight. Thanks!

sounds normal i guess, hard to tell if there is anything wrong without a pic.
but its a neck, they are typically the skinniest part of the snake.

My mom wonders about the same thing, Lol.

yeah that sounds like a ball python to me...check out the pics section on here and see if your snake looks like the ones posted...or better yet post a pic and we can get a better grasp of what you are talking about
