Bsc Preferred M3343 Square Corrugated Mailing Tubes 25-pack

Product Description

The BSC PREFERRED M3343 is a pack of 25 flat-shipping, one-piece square corrugated mailing tubes designed for packaging and shipping applications. Unlike traditional round mailing tubes, the square profile eliminates rolling during handling, making them easier to stack, store, and ship. Each tube is constructed from 200/ECT-32-B white corrugated board and assembles without tape or glue. The flat-pack design saves significant storage space until the tubes are needed. These are a practical choice for mailrooms, fulfillment operations, and shipping departments that move documents, posters, or other rolled or rigid items at volume.

These square mailing tubes are suited for light commercial and professional shipping environments where standard round tubes present handling or storage challenges. The self-locking, one-piece construction speeds up packing workflows without requiring additional fastening materials. Sold as a pack of 25 units, they fit standard fulfillment and distribution center workflows. This product is equivalent to part number S-1580.
