Plarail bridge piers and mini bridge piers. There are four types as shown in the photos. I wanted to list them quickly, so I haven't cleaned them. There may be dust and other debris. They will be shipped in a Shinkansen box. They are sturdy enough that a small child might be able to sit on them, but I'm not sure if they are designed to be sat on, so please use them at your own risk. The lid is tight and a little difficult to close. The non-woven fabric on the inside of the box is torn. Thank you for your consideration. ........
