These Buick Yip dummies have arms where the tips are level with each other (and if you draw a line through them, that line is parallel to the floor). The traditional setting for arms is to have the tip of the left side (when facing the dummy) about 1-2 inches higher than the right. If you turn the arms on these dummies upside down when inserting them it will be very similar to the traditional arm set, making these dummies really good for people that like both traditional AND level/parallel arms.
