Leather Is a Material, Not a Product — Know Which One You Have
This guide covers leather as a material — jackets, outerwear, bags, cases, and craft goods — and the material's behaviour is what dictates the packing. (For the specific categories, our handbags, belts, and wallets guides cover their own structural and authentication quirks.) The first thing worth knowing is that 'leather' spans wildly different things. Full-grain leather retains the hide's natural surface and develops patina; top-grain is sanded and finished; and the confusingly-named 'genuine leather' is a lower grade of split hide. Suede and nubuck are napped surfaces that mark and water-stain almost on contact. Patent leather has a lacquered finish that can stick to plastic and transfer.
That variety matters because the packing rules diverge. A rugged full-grain jacket tolerates handling that would ruin a suede one. Patent leather must never be wrapped in plastic that can bond to its surface in heat. Suede should not be pressed against anything with texture, because the nap takes an impression. Identify the material honestly — in your listing and in your packing — because a buyer paying full-grain prices for split hide will find out, and a suede jacket packed like a leather one will arrive marked.
Mold, Moisture, and the Enemy That Grows
Leather is skin, and skin holds moisture. Seal a leather jacket in an airtight plastic bag for a multi-day transit — or ship it slightly damp — and you can create precisely the warm, humid, dark environment in which mold grows. Mold on leather is not a cosmetic problem: it feeds on the hide, it leaves stains and a persistent smell, and once established it is genuinely difficult to remove. This is the leather-specific disaster that catches sellers who packed carefully in every other respect.
The prevention is to let it breathe while keeping the weather out. Ship leather dry and clean — never damp, never freshly conditioned with oil that hasn't absorbed. Use a breathable dust bag or cloth against the leather rather than sealing it in plastic, and put the moisture barrier on the OUTSIDE of the packaging (a poly-lined box or a waterproof outer layer) so rain can't reach it while the garment isn't sitting in its own humidity. A silica packet in the box helps. And don't compress it: the tips above are right that leather needs a little space, because tight compression against a box wall over days leaves marks the hide remembers.
⚠️ Never seal leather in airtight plastic for shipping, and never ship it damp. Trapped moisture plus days in a warm truck is how mold starts — and mold on a hide stains, smells, and is very hard to reverse. Breathable inside, waterproof outside.
Jackets: Shape, Creases, and the Weight Nobody Expects
Leather outerwear is the heavyweight of this category. A full leather or shearling jacket is genuinely heavy — several pounds — which puts it well outside the featherweight bands and into real postage territory, and it's bulky enough that a box, not a mailer, is usually the answer. Weigh and measure before quoting, because sellers routinely underprice shipping on a jacket by assuming it packs like a garment rather than like a small piece of furniture.
The packing objective is to avoid setting creases in hide that will hold them. Fold as little as possible and as gently as possible; stuff the shoulders and sleeves with tissue or paper so they hold their form rather than collapsing flat; and interleave tissue at any fold so the leather bends around a radius instead of taking a hard edge. Shearling and heavily-lined jackets resist compression and should not be forced into an undersized box. Where the piece is valuable, a larger box with the jacket loosely arranged is worth the postage difference — a permanent fold line across a leather back panel is not something a steamer fixes.
Selling Leather: Condition, Patina, and the Smell Test
The used-leather market is knowledgeable, and its buyers read condition carefully. Photograph the grain up close (it shows the quality), the lining and its condition (linings tear long before hides do), the zippers and hardware, the seams and stitching, and every scuff, crack, or dry patch. Cracking is the flaw that matters most, because it indicates hide that has dried out and lost its integrity — it should always be disclosed. Distinguish honestly between patina (desirable, a sign of good leather aging) and damage (cracking, deep scarring, mold staining); vintage leather buyers actively want the former and will not forgive an undisclosed instance of the latter.
Two disclosures sellers routinely skip and shouldn't. Smell: leather absorbs odors — smoke, mildew, mothballs — and holds them tenaciously, and a jacket that reeks of cigarettes when the box is opened is an immediate return. Say so if it does. And previous treatment: a hide that has been over-oiled, dyed, or repaired should be described. Clean it, dry it thoroughly, let it breathe in the box, protect it from rain on the outside, and describe it truthfully — leather that arrives dry, unmarked, and honestly represented is what makes this market work.
