Wooden track parts from Can Do. I'm giving these away because I no longer play with them. The straight track pieces have grooves on one side only. The curved track pieces have grooves on both sides. They are compatible with Brio wooden rails and can be connected. - Material: Wood - Shape: Straight and curved - Number of pieces: 16 straight, 6 curved Thank you for looking. #ModelRailroad #Plarail #Brio #Kotetsu (Train enthusiast) #TrainLover #TrackParts #CanDo
