Cut packaging costs with our snap seel tubes. Their strong cardboard 3-ply spiral wound construction resists bending and keeps your shipment safe during the transportation. Our snap seal mailing tubes seal in a pinch; the ends of snap seal tubes are pre-scored in a way that they simply fold in to seal closed. Not only these sturdy crimple end tubes save you time, but they also save you on the cost of the mailing tube. Sizes shown are usable space. Actual tube lengths are greater.
