## Description

Small businesses shipping lightweight, non-fragile items need packaging that is easy to prepare and suited to everyday orders. METRONIC poly mailers offer a practical format for apparel, accessories, and other soft goods.

Each black mailer measures 12 x 15.5 inches and closes with a peel-and-seal adhesive strip. The 500-count pack gives businesses a ready supply for recurring shipments.

When an order needs rigid protection, a box may be the better format, for flexible items such as shirts or jeans, these lightweight mailers provide a streamlined alternative.

## Tips for day-to-day use

Place the item inside the bag, peel the adhesive strip, and fold the closure over to seal. The self-sealing design keeps packing straightforward across a run of orders, while the rectangular shape accommodates many common apparel and accessory shipments. For a small business preparing clothing orders, the 12 x 15.5-inch size offers a consistent mailer format to keep on hand.

These bags are made from polyethylene and are described as water-resistant, tear-resistant, and puncture-resistant. Their lightweight construction and tamper-evident closure are useful features for routine shipping, and the black exterior gives packages a consistent, understated look. They are intended for lighter, non-fragile products, including shirts, shoes, jeans, books, and cosmetics.

Buyer feedback highlights the mailers’ sturdy feel and thickness. That makes the construction a notable consideration for sellers choosing a flexible shipping bag for apparel and similar items.

## Why it makes sense

A box is useful when an item needs a rigid container, while a poly mailer is a more fitting approach for soft goods that can ship in a flexible package. This pack is designed around the latter need: each bag is lightweight, closes with an adhesive strip, and has a water-resistant polyethylene construction. Having 500 of the same size on hand can also help a shop use a consistent package for suitable orders.

For example, a seller packing a folded shirt can place it in the mailer, seal the flap, and prepare it for shipping without building a box for that order. The format also suits accessories and other lightweight, non-fragile products that fit within the bag.

## Final verdict

METRONIC’s 12 x 15.5-inch, 500-count poly mailers are built for businesses that regularly ship apparel and other lightweight, non-fragile goods. Their peel-and-seal closure, polyethylene construction, and practical bulk quantity make them a useful everyday packaging choice when a flexible mailer fits the shipment.
