An open end carrier construction for conveying folded paper or paper-like slips between terminal stations in pneumatic tube systems. A hollow carrier body is formed with open ends, one end of which is closed by a disc and cap. The carrier body is double-concave and forms a narrow inner passage or slot intermediate the carrier ends through which folded slips extend and in which the slips are securely gripped when inserted in the carrier body through the uncapped end.
