These are compact slope piers for Plarail, more compact than the mini piers and sloped curve rails. This is a set with double the number of parts of the products I am selling separately. Very simple and sized not to protrude from the rail width. It can also be used with double-track rails, making it easy to create elevated lines, three-dimensional layouts with double tracks, figure-eight layouts, etc. Slopes can be created on both curves and straight lines. As a bonus, four compact elevated bridge piers with the height of the Plarail genuine piers are included. Using these, you can create grade separations without using block piers. However, please be aware that the running may become unstable. A video about this product is available on Youtube, so please refer to it. https://www.youtube.com/shorts/GSdDRla7hBs Set contents Compact Slope Pier (Low) x 8 Compact Slope Pier (Mid) x 8 Compact Slope Pier (High) x 8 Compact Elevated Pier x 4 *This product is a personal production part made with a 3D printer.
