What fits in a 9x12 poly mailer

  • A T-shirt or tank top folded to about 8" x 10"
  • Leggings, swimwear, scarves and bundled socks
  • Letter-size paperwork, catalogs and flat prints (an 8.5" x 11" sheet just fits)
  • Soft accessories such as hats, gloves and zip pouches

Sizing tip: add your item's thickness to its width and to its length. Both totals have to fit inside 9" x 11". A T-shirt folded to 8" x 10" and 1" thick comes to 9" x 11" — a snug fit.

FAQ

Will a folded hoodie fit in a 9x12 poly mailer?
Usually not. Most hoodies fold to at least 9" x 11" and 2" to 3" thick, which needs the 12x15.5.

Are 9x12 poly mailers padded?
No. They are flat poly bags without a bubble lining, made for clothing and other items that can't break.

How many come in a case?
1,000 mailers per case, all one color.
