Abstract: A suitcase connectable to another suitcase includes: a first connecting portion disposed on a front surface of the suitcase, and a second connecting portion disposed on a rear surface of the suitcase. The first connecting portion is operatively associated with the second connecting portion to connect at least two suitcases front to rear. The suitcase further includes a front pair of wheels mounted along a first axis, and a rear pair of wheels mounted along a second axis parallel to the first axis, wherein the front pair of wheels is spaced apart laterally a first distance, and the rear pair of wheels is spaced apart laterally a second distance larger than the first distance, so that when the at least two suitcases are connected front to rear, the front pair of wheels of the rear suitcase nest between the rear pair of wheels of the front suitcase.
