Set of 3 suitcases. Large one measures approximately 34 x 24 x 15 inches. Medium one measures 31 x 20 x 13. Small one measures 21 x 15 x 10. They fit inside each other for easy storage. They are all on rollers and have a zipper to expand for additional packing. The small one has been used quite a bit and the telescoping handle is broke off of it. The two larger suitcases have not been used as much and are still in really good shape.
