There is a path I walk every morning. Each house has a different color in their yard and varying heights of trees, yet the mailboxes lined up along the road are remarkably similar no matter which house you pass. Whether it's a newly built home or an old one, the mailbox standing guard in front seems to come from the same mold.

The body has a rounded roof that curves gently like a tunnel, and each side has a small red flag. When there's a letter inside, the flag is raised, and when it's empty, it's lowered; this method is the same in every alley. Even though it's a scene I pass by every day, there are days when I suddenly wonder why that is.

As I searched for answers, I found that the story goes back over a hundred years.

In 1915, the U.S. Postal Service established the standard specifications for mailboxes to be installed on rural delivery routes for the first time. The person responsible for this design was Roy Joralmon, an engineer with the postal service, and the tunnel-shaped body with a red flag he sketched became the prototype of the mailbox we think of today. Starting in July 1916, mailboxes that did not meet this standard could not be installed on rural delivery routes, meaning standardization began much earlier than one might think.

There's an interesting point to note. Joralmon did not patent this design. Thanks to that, any manufacturer could use this shape, and over a century, similar silhouettes of mailboxes have appeared along roadsides across the United States. It's touching to realize that because someone didn't seek to claim ownership, this design became widely adopted.

Not much has changed even now. The U.S. Postal Service does not specify the color or exterior appearance of mailboxes in detail. Instead, they only set minimum functional standards, such as whether the door opens and closes properly, whether it withstands wind and rain, whether the flag operates correctly, and whether the interior space is sufficient for holding mail. As long as these standards are met, there's freedom to paint or decorate them, yet they ultimately converge into similar shapes, suggesting that good design may inherently be limited to a few forms.

Perhaps that's why, as I walk through the neighborhood, I notice the subtle personalities of each mailbox. Some have small bird-shaped decorations on the side, while others have flower pots underneath that change with the seasons. The structure of the body is the same, but the personal touches added on top feel endearing.

I encounter similar moments when tending to my garden. As long as the boundaries of the flower bed are neatly defined, the flowers can bloom freely within without making the whole look messy. This is also true when I line up lavender pots. The shapes of the pots are all the same, but the scents and colors that grow inside spread out differently. I think of mailboxes as similar vessels. They only have a minimal form defined, yet the stories that pass through them are always different.

Because I enjoy working with scents, I often find myself drawn to these things. Whether it's lavender or rosemary, they may look similar when bottled, but the moment you open the lid, the scents are never the same. Perhaps the ability to contain different stories within a unified vessel is a common trait of things that are cherished over time. Mailboxes, too, may appear silent on the outside, but they always hold someone's story inside.

This morning, I passed by a mailbox with its flag raised. I don't know what news is contained within, but it felt heartwarming to realize that a blueprint quietly drawn by someone a hundred years ago is still fulfilling its purpose today. It was another morning to confirm that there are things that last without needing to show off, found in such small scenes.
