Does the stated mailer length include the flap?
Dimension conventions vary. Mark the usable internal length and the flap or sealing allowance separately, and confirm how the quoted dimensions are measured before ordering.

Before you choose
Mailer outside dimensions and usable internal dimensions can differ. Closures, seams and any lining affect the available space, so show usable width and length separately from a flap or sealing allowance. Include the packed item’s width, length and thickness, then review a fit sample. This product route remains for non-food packaging.
Review packed-item dimensions, closure and mailer fitDimension conventions vary. Mark the usable internal length and the flap or sealing allowance separately, and confirm how the quoted dimensions are measured before ordering.
A three-dimensional item takes up more than a flat outline. Its thickness belongs in the fit review along with width and length, especially when the bag must close around a box or a folded product.
Describe the intended opening and second closure in your brief. The material and closure layout require review; a standard self-seal description alone does not confirm a return-use feature or food-contact suitability.
