Gap Gray Turtleneck Sweater

Condition is like new, I think I wore it twice. Thick, soft quality fabric. Light gray with a subtle hint of blue. During inspection I found one small discoloration at the back of the neck, which falls under the turtleneck anyway. Not sure how that happened, shown in last 2 photos. Neck can be worn up a little or laying down flat. 5 functional buttons up the neck. True to size. Questions and offers welcome!
