- What can fit in a 14 1/4 x 20 inch mailer?
- Folded shirts, sweaters, books, small boxed electronics and documents. The usable space is slightly smaller than the listed size because of the seal flap.
- Do these need tape to close?
- No. The peel-off strip exposes adhesive that seals the flap. Many shippers add a strip of tape over the seam for extra security on heavy items.
- Are they waterproof?
- No. The kraft paper outer resists scuffs but absorbs water. For rain-prone routes, use a poly mailer or bag the contents first.
- How does #7 compare with smaller sizes?
- #7 is among the largest padded mailers, close to a small shipping box in capacity. Choose #0 to #2 for jewelry, phones and small accessories.
- Can I write on them?
- Yes. The paper surface takes pen, marker and adhesive labels well, which is why many sellers prefer kraft over poly.
