Corrugated cardboard folding mailer boxes, 185 x 135 x 110 mm, 50 pcs

Why it is on the list

A single-wall corrugated (FEFCO 0427) fold-flat box that gives a rigid alternative to poly mailers for small goods.

Watch out for

Single-wall board protects less than double-wall, and the box still needs paper tape or another closure.
