About this mailer
Stock sizes are a compromise, and at volume that compromise costs money. A mailer that is an inch too big wastes material, invites the contents to shift and get damaged, and can push a parcel into a higher dimensional-weight bracket. Custom-size bubble mailers solve all three at once by being built to your product’s actual dimensions — snug protection, minimum waste, and the lowest postage tier your item honestly qualifies for.
You are not limited to one material, either. A custom mailer can be produced in white poly, natural kraft, metallic, holographic, or compostable construction, so you keep the exact brand finish you want while gaining a size that fits. We start from a dieline drawn to your interior dimensions, confirm it with you, and proof your full-color artwork — front and back, edge to edge — before anything is tooled or run.
Custom sizing also opens up construction options that stock mailers rarely offer: a second peel-and-seal strip for easy returns, a tear-strip for fast opening, a return flap, or a gusseted base for bulkier items. These are the details that make a subscription unboxing feel designed rather than shipped, and because the run is yours, they are matched identically on every reorder.
The economics reward scale. Custom tooling can raise the minimum above our standard 500, so custom-size mailers make the most sense once you have settled on a repeating product and are ordering into the thousands or tens of thousands. At that point the material and postage savings from a right-sized mailer typically pay for the tooling many times over. We keep your dieline and artwork on file so every future batch matches exactly.
Tell us your product’s dimensions, the finish you want, and any construction features you have in mind. We will draw a dieline, show you a photo-real mockup, and quote it — free, so you can see the material and postage math before you commit.
