About this carton
Custom mailer boxes are the workhorse of modern e-commerce, and this is our most-ordered carton for a reason: it turns a shipment into a brand moment. The roll-end tuck-front build locks together without tape or glue, protects product through the parcel network, and gives you two fully printable surfaces — a branded exterior that stands out on a doorstep and an interior reveal that photographs beautifully for the unboxing.
We print these full-color CMYK on E-flute corrugated, which keeps the wall thin enough for clean folds and crisp graphics while still absorbing drops and compression in transit. Choose a natural kraft look for a sustainable, no-bleach aesthetic, a bright White SBS liner when your artwork needs punchy color, or a dramatic matte-black stock for premium and beauty brands. Every run can carry a custom Pantone match, a foil-stamped logo, or a soft-touch laminate that makes the box feel considerably more expensive than it costs.
Because they ship flat and pre-scored, custom mailers are efficient to store and fast to pack — your fulfillment team folds one in a few seconds, drops the product in, and closes the tuck. That matters when you’re shipping hundreds of units a week. It also means freight and warehousing costs stay low, since a pallet of flat mailers takes a fraction of the space of pre-formed boxes.
Typical orders start at our 100-unit minimum for brands testing a new SKU or a limited drop, and scale into the tens of thousands for established subscription programs and DTC catalogs. We keep your dieline and artwork on file so reorders match your last batch exactly — same size, same color, same feel — with no re-setup. If you’re not sure what dimensions you need, send us the product (or its measurements) and our designers will spec a snug fit that minimizes void fill and dimensional-weight shipping charges.
Send your logo and brand colors and we’ll return a photo-real mockup within 24–48 hours, revise it free until you approve, and only charge once production starts. Get a custom quote and we’ll include bulk pricing across a few quantities so you can see where your per-unit cost lands.
