Bags for men? Or women?

Postalco items have always been non gendered. Beginning with the very first Legal Envelopes we made back in 2000.

Material

Mill Leather

We chose this leather for its luxurious soft touch and the way it fits the body. Dyed to preserve natural color variations that are the trademark of beautiful leather. Full grain cowhide. Leather certified to be sustainable and responsible: best practices in traceability, energy consumption, water usage, air quality, emission control and worker safety. Made in facilities certified by The Leather Working Group (LWG). Tanning completed with REACH compliant ingredients. (REACH is a regulation of the European Union that restricts chemicals, heavy metals, and pollutants in consumer products including leather items).

Care

 

To keep the natural surface of this material we have only coated this leather with a light water resistant treatment. Naturally finished leathers and materials may crock or rub off. Please take care to keep your item dry. If it gets wet in the rain or with water it is more likely for the colors to crock. If it does get wet pat dry with a soft cloth. Shade dry. To help blend in small scratches and dirt marks please moisten a soft cloth with water and wipe gently. Be sure to wipe the overall surface, not just in one area to avoid staining. Shade dry. Oily leather creams will stain this bag so we don’t recommend them. If the surface gets dry, please use a mild creme (such as clear Delicate Shoe Cream) to replenish the moisture. Be sure to use only clear cream as any color will rub off! At Postalco to get the leather moisturizer into the nooks and crannies we use a toothbrush to apply the cream.

Gift Wrapping

Gift wrapping may be a cloth bag or a paper bag. Wrapping materials used will vary depending on the product type and size. Please note that we are not able to accept requests for specific wrapping materials. If you would like to have multiple items wrapped together, or if you would like to wrap only some items, please tell us in the memo box. If you do not specify, we will wrap each item individually.

Example of what to write in the memo field:
"Notebook (light blue) and notebook (dark blue) gift-wrapped together, and Bag- gift-wrapped separately. etc. "

Postalco cannot take responsibility for any shipping delays due to customs clearance, payment transaction delays, or any unforseen circumstances.
Import taxes, duties, and related customs fees may be charged when the parcel arrives at the destination country. The payment of these charges and taxes is the responsibility of recipient and will not be covered by Postalco. Duties & taxes are set by the customs authorities of the destination country. We estimate the value to be between 25-40% of the amount paid for the item(s) ordered. The shipper will contact you directly requesting payment upon your order's arrival through customs.
All shipments outside Japan include a commercial invoice to avoid delays in customs. We are unable to indicate a lower price for the value of your order listed on your commercial invoice as we must adhere to all international import/export rules and regulations.
Unclaimed packages: The shipper will leave a notice if nobody is available to sign for your package. The shipping agent will hold your package for a few days only. If you do not claim it, it will be returned to us, marked unclaimed. You will be required to pay for shipping twice to have your order sent a 2nd time. There may be some countries we cannot ship to due to courier restrictions.

More details Right

Unique hardware
Made by a master metal craftsman in Japan. It took us more than a year to develop this brass hardware.

Our original U-Lock
Inspired by old parachuting hardware, this lock opens and closes with one hand. In a smooth movement, pulling up on the U-part lifts the flap.

Drawings for the U Lock
This hardware started with a dream of a piece of hardware that only had a U-shape visible.

Paper Prototype for the U Lock

Luxurious inner lining
We used leather for the inner lining so it feels great to the touch and you can use the bag for years to come.

Comfortable shoulder strap
Rounded edges that don’t dig into your body. Also, the shoulder pad reduces the strain on your shoulder. Extra adjustable so you can wear it long or short and match any look.

Back pocket
Open back pocket for instant access to phone or other small essentials.

Inner pocket
Inside zipper pocket so your essentials stay secure.

Sharks
Looking at a picture book of dinosaurs there was a creature with a shell and long neck like a turtle but with sharp teeth jutting out. Mind-bending. I was surprised to see in the middle of these wildly shaped dinosaurs, a regular looking shark! I guess sharks nonchalantly swam around then just the way they do now. Other dinosaurs are gone, but the shark survives. There must be something about sharks that works.

Sharks & Mail Bags
Sharks are like mailbags that postmen carry. Since the Middle Ages messengers' leather mail bags have not changed much. Slung diagonally over the shoulder so that you can move the bag easily from the back to the front of the body for quick access. A flap protects letters from the rain. Like sharks, mailbags survive.

Make it last
We’re at a turning point where we can't just keep throwing everything away. Things that last a long time, and look good doing it, mean a less disposable daily life.

Mill leather
We chose this leather for its luxurious soft touch and the way it fits the body. Aniline dyed to preserve natural color variations that are the trademark of beautiful leather. Full grain cowhide. Leather certified to be sustainable and responsible: best practices in traceability, energy consumption, water usage, air quality, emission control and worker safety. Made in facilities certified by The Leather Working Group (LWG). Tanning completed with REACH compliant ingredients. (REACH is a regulation of the European Union that restricts chemicals, heavy metals, and pollutants in consumer products including leather items).

Learning from Japan
The craftspeople, suppliers, and small workshops found in Japan make things not to be found anywhere else. We are fortunate to work with family businesses that are so focused on their craft. Don’t put Postalco items on a shelf or in a drawer. Their beauty is revealed through daily use. They will help you feel good at home and be ready in a meeting.
