Plarail Slope Rail Set - Expanded Layout Version - Continuous Spiral ■Included: Straight rails x 2 Bridge piers x 15 Mini bridge piers x 14 Curved rails x 12 Small iron bridge frames x 2 1/2 straight rails x 2 New slope rail x 1 Slope curved rail A x 4 Slope curved rail B x 8 Catenary poles x 4 Please note that there are scratches and dirt from use. The slope curved rails seem to be made of a slightly softer material, making them feel easier to use than the regular ones. I've also included the construction process, so please use it as a reference! I think you can expand it even further if you have other rails, so give it your best shot! It will be shipped in a recycled cardboard box. Please purchase with the understanding that this is a used item.
