Letterbox-Sized Packs

Letterbox-Sized Packs

Small items don't always need a full-sized box. A letterbox-sized pack is thin enough to fit through a standard mail slot, which can mean faster delivery and lower shipping costs for the right product. Hale Path Packaging builds custom letterbox-sized packs USA brands use for small, lightweight items that don't need much depth.

  • Quick delivery, anywhere in the USA
  • A satisfaction guarantee on every single order
  • Help with design from first idea through to final artwork

Why Thickness Is the Whole Game Here

A letterbox pack only works if it stays under a strict thickness limit. Go even slightly over, and it stops qualifying for the lower shipping rates this format is built around. We work with jewellery brands in Portland and small accessory sellers in Tampa, and thickness is the first thing we check on every design, before anything else gets finalised.

Getting the Thickness Right Without Crushing the Product

Staying thin doesn’t mean skipping protection. It means being precise about where that protection goes. We use thin, targeted padding and smart internal structure instead of a thick outer wall, so the product stays safe without pushing the pack over the limit.

Measured and Made In-House

We handle design, cutting, and printing in-house, and every letterbox design gets measured against the thickness requirement before it’s approved.

  • Made at our own USA site, keeping turnaround short
  • Thickness gets measured at every stage of design
  • A free sample comes before any full production run
  • Built specifically with small, lightweight products in mind

How a Portland Jewellery Brand Lowered Its Shipping Rate

A jewellery brand in Portland was shipping small items in a box that was just over the letterbox thickness limit, without realising it, which meant paying a higher shipping rate on every single order. We redesigned the pack with thinner, more targeted internal padding that still protected the product, and brought it safely under the limit. Shipping costs on that product line dropped noticeably the very next month.

Features Built Into Every Letterbox Design

  • Measured precisely to stay within standard thickness limits
  • Targeted internal padding instead of thick outer walls
  • Sized close to the product to avoid wasted space
  • Full-colour print available on the outside

The Recurring Issue We Watch For

Most problems with letterbox packs come from a design that looks thin enough but measures just over the limit once it’s actually assembled. We measure final assembled thickness, not just the flat die-line, before any design is approved. That same careful-measurement approach carries into our Compact Powder Boxes USA work too.

How We Confirm a Design Actually Fits

We don’t rely on the flat die-line measurements alone, since a pack can read as compliant on paper and still come out slightly thick once it’s assembled and filled. Every letterbox design gets physically assembled, filled with a sample product, and measured before we confirm it meets the required thickness.

When This Format Makes Sense

If your product weighs very little and sits under about an inch thick, this format is worth exploring for the shipping savings alone. For anything bulkier, our Custom Trading Card Booster Packaging line is probably the better starting point.

Frequently Asked Questions

What products fit a letterbox-sized pack?

Anything small, light, and fairly flat. Jewellery, additions, cards, and prints are the usual choices, and some small electronics fit too. If you can slide it into an envelope-sized pack without forcing it, it's probably a good candidate.

Will my product still be protected in such a thin pack?

It will be. A thin pack doesn't mean thin protection. Instead of making the outer wall thicker, we put the padding inside, right where your product needs it, so it stays put and gets through shipping in one piece.

Can these packs be branded?

Yes. We print full colour on the outside, so your logo and artwork are the first thing customers see when the pack shows up at their door.

Is there a minimum order?

We keep minimums manageable, so you don't have to order a huge batch just to try the format. It works well if you're a smaller brand and want to see how it goes before ordering more.

How long does a first order take?

Most first orders take two to three weeks from the day you approve your artwork. If your files are ready to go early, you'll get the pack in your hands sooner.

Are letterbox-sized packs recyclable?

Yes. They're made from standard paperboard, which almost any recycling program in the USA accepts. Customers can just flatten the pack and toss it in with their other recycling. Hale Path Packaging builds letterbox-sized packs measured precisely to stay within shipping limits, without cutting corners on protection.

We wanted luxury but eco-friendly. They suggested recyclable rigid boxes with a frosted window and satin insert. Customers now post unboxing videos; that’s how good they look.
