Product guide

METRONIC 6 x 9-Inch White Poly Mailers, 1,000 Count

METRONIC poly mailers are white 6 x 9-inch self-sealing shipping bags sold in a 1,000-count pack. Their lightweight polyethylene construction suits small, non-fragile items, while the listing describes them as opaque and water-resistant in use.

At a glance

Self-sealing adhesive closure avoids a separate closure for each mailer.
The listing suggests these bags for lightweight, less fragile items such as clothing, socks, accessories and small products.
The stated 6 x 9-inch size makes these a small-mailer option rather than a padded package.
