I am selling these items because my child has outgrown Plarail. Used for about 10 years. Includes 16 half-straight rails. Some were hand-me-downs, and some were purchased. 13 light blue rails, 2 dark gray rails, and 1 light gray rail are believed to have come from a set. These items have been used by a child and show signs of wear and tear over time. They were stored together with other rails in a case after use, so they are generally in poor condition with scratches. Even among the light blue rails, there are slight color variations, and some have marks that look like bite marks (see photos 13-15). After washing and wiping with disinfectant wipes, there may still be small stains or dirt remaining in complex grooves. Some rails are difficult to connect/disconnect, and some are loose. Please check the photos and understand the condition before purchasing. Thank you.
