METRONIC 10x13 Poly Mailers, 200-Pack White Waterproof Self-Seal Bags

For small businesses and individuals shipping clothing or other lightweight, soft goods, these 10x13-inch METRONIC poly mailers provide a simple alternative to a rigid package. Their white, opaque polyethylene material helps keep the contents out of view during mailing.

A self-sealing adhesive strip closes each bag without a separate closure. The mailers are also described as waterproof, dust-resistant, puncture-resistant, and tear-resistant, useful features when sending apparel and other less fragile items.

Buyers often highlight the bags for clothing shipments and appreciate the adhesive seal. Feedback on durability and thickness is mixed, so these mailers are best considered for the soft goods and light items they are designed to carry.

How to use it

Choose a mailer for a lightweight item that does not need the rigid structure of a box, such as a shirt, clothing accessory, or book. Place the item inside, leave room at the opening, and press the adhesive strip closed to seal the package. The opaque material keeps the contents concealed, while the water-resistant construction adds a practical layer of protection for everyday mailing.

For an apparel order, the 10x13-inch format gives you a ready-to-use envelope rather than requiring a box for a soft item. The self-sealing closure also keeps the packing process straightforward: load the bag and close its adhesive flap. Buyers commonly report using these mailers for shirts and other clothing, and many appreciate how the strip adheres. Some buyer feedback differs on how well the bags withstand tearing and on their thickness, which is useful context when choosing packaging for a shipment.

What you get

The pack contains 200 white, 10x13-inch polyethylene mailers. Keeping a multipack on hand can suit a small shop sending recurring apparel orders, as well as personal mailing needs for lightweight, soft goods.

Their waterproof, dust-resistant design and pack of 200 make them useful for regular shipping as well as occasional personal packages. Choose this envelope-style approach for lightweight goods that can be mailed without the rigid structure of a box.
