This is a BRIO rail set. It's a little hard to see, but there are markings on the rails. You can connect it to your existing rails to create a layout with slopes. Includes: Slope rails x 2 Curved rails x 4 Bridge piers x 5 I think one of the bridge piers is not BRIO (see images 7-9, marked with ↓). It shouldn't affect play, but the shape is slightly different, so please place it on top when using them stacked. If you don't have any rails, I can add 4 curved rails for 500 yen to create a complete circular layout. Please let me know in the comments if you'd like this. There are no cracks or chips, but there are scratches and dirt. Please check the condition carefully in the images. Please understand that this is a used item before purchasing.
