Cube mailers for compact items

These white corrugated literature mailers measure three inches on every inside dimension, giving a small cube for books, binders or sample kits. The single-wall B-flute construction carries an ECT-32 rating and a 65 lb maximum load. Each carton contains fifty mailers ready for immediate packing.

Flat storage and simple assembly

The mailers arrive flat and fold into a rigid cube without tape or glue, freeing shelf space until they are needed. Corrugated cardboard is one hundred percent post-consumer recyclable, so used units enter standard recycling streams. No special tools or equipment are required to build each box.

Shippers sending uniform small parcels

This pack suits operations that repeatedly ship items fitting a three-inch cube and want a consistent box size. Buyers who need larger dimensions, heavier-duty walls or varied box assortments should look at other mailing supplies.

Questions about this item

Will the 65 lb maximum load hold up when I stack these mailers all day?

The ECT-32-B single-wall construction is rated for 65 lb maximum load, so it handles steady stacking within that limit.

Does the B-flute corrugated cardboard trap heat or make noise in a busy mailroom?

Corrugated cardboard is silent and does not generate heat; the B-flute profile simply adds rigidity without any thermal or acoustic impact.

Do I need tape or strapping to close each 3x3x3 in mailer?

Yes, the flat literature mailer arrives open and requires tape, glue or strapping — none of which are included in the 50-count pack.
