Bsc Preferred M3325 Square Corrugated Mailing Tubes 25 Pack

Product Description

The BSC PREFERRED M3325 is a pack of 25 flat-shipping, self-locking square corrugated mailing tubes designed for packaging and shipping operations. Each tube is constructed from 200/ECT-32-B white corrugated material, providing reliable crush resistance for items in transit. The square profile eliminates rolling during handling, staging, and transport, making palletizing and stacking more predictable. Tubes ship flat to reduce storage footprint and fold into shape quickly without tape or glue, cutting assembly time at the packing station. This SKU is sold as a pack of 25 units.

These square mailing tubes are suited for mailrooms, fulfillment centers, print shops, and any operation that ships rolled or elongated items such as posters, blueprints, documents, or textiles. The one-piece fold-up design keeps assembly simple and reduces the need for additional closure materials. The white corrugated exterior presents a clean, professional appearance for outbound shipments. Warehouses and shipping departments with high daily volume benefit from the flat-pack format, which allows bulk storage of large quantities without dedicated rack space for pre-formed tubes.
