3 x 3 x 18" 32 ECT Square Corrugated Mailing Tubes (25 / bdl.)

With their unique square shape, our tubes make it an effortless experience to insert and retrieve your contents. Rolling is never a problem either – the conveyors won’t move these robust boxes constructed from 32ect-B oyster white corrugated! Best of all; no need for pesky tape thanks to the integrated locking tabs.
