Pin-striped motleys are those motleys that show the thin striping anywhere from the joining of a couple saddles to the entire length of the snake. The stripes on these motleys are much thinner than the wide stripe of a genotypic stripe. The genotype of pin-striped motleys may be motley or motley/stripe.
Those pin-striped motleys with circles on the ends are often called "Q-tipped" motleys, a variation of pin-striped motley. The first photo below is a Q-tipped anery motley, the second is a pin-striped caramel motley. The others are anery motleys with varying amounts of pin-striping.
