Includes BRIO, IKEA, and some unbranded items. Everything is shown in the first photo. All the rails are shown in photos 16 to 20. Each photo shows one piece. Some are single-sided, and some are double-sided. One of the door knobs is worn and comes off easily. These are used items that have been used by children. There are small scratches and discoloration. Shipping is planned via Yu-Pack. I inspect items carefully to ensure they can be used comfortably, but I am not a professional. Please refrain from purchasing if you are concerned about minor details. There are no smokers in the family, and we do not have any pets. Please also see my profile.
