Square Mailing Tubes 3 x 25 in Oyster White - Stable, Easy to Assemble

In this review the Partners Brand PM3325 Square Mailing Tubes are examined for artists, small businesses, and anyone who ships rolled or flat artwork and documents. The bottom line: these 3 x 3 x 25 in square tubes are best for users who need a stable, easy-to-pack mailer that eliminates rolling and assembles quickly without tape or glue, saving time during packing and space in storage.

Key Features

• Square design: The square profile prevents tubes from rolling in transit or on a workbench, making them easier to handle when packing multiple items.
• Ships flat: The one-piece tubes ship flat to save storage space and reduce clutter in a studio or shipping area until needed.
• Tool-free assembly: Tubes fold together fast without tape or glue, which speeds up packing and reduces consumable costs.
• Durable corrugated board: Constructed from 200#/ECT-32-B white corrugated for sturdy protection during shipping and handling.
• Proudly made in the USA: Domestic manufacture means consistent construction and faster availability for US-based buyers.

Who It's For

These square mailing tubes are ideal for artists, photographers, print shops, craft sellers, and small businesses that ship framed prints, posters, or rolled artwork up to 25 in long. The anti-roll shape and lightweight construction make them useful for packing on-site before travel or when loading many packages into a vehicle.

Those who need heavy-duty waterproof shipping or specialized end-cap security might look elsewhere; these tubes are sturdy and well suited for typical artwork and documents but are not described as water-resistant or as having tamper-evident closures.
