These compact slope piers are smaller than Plarail's mini piers and sloped curved rails. They are very simple and do not extend beyond the width of the rails. The piers are yellow, similar to the standard Plarail pier color. They can also be used with double-track rails, making it easy to create three-dimensional double-track layouts, figure-eight layouts, and more. I am also selling the same product separately, but this is a 2x value set.
