Made to age well

Let it patina.

Full-grain leather is meant to be used. With time it darkens, softens, and takes on the marks of everyday carry — that character is the point, not a flaw. No treatment is needed to earn it.

Water and heat.

• Avoid soaking. If it gets wet, blot with a dry cloth and let it air-dry away from direct heat.
• Don't use a hair dryer, radiator, or sunny windowsill — fast heat dries and cracks leather.

A little, now and then.

• Every few months, work a small amount of neutral leather conditioner in with a soft cloth.
• Test on an inside edge first, apply thin, and buff off the excess — less is more.
• Skip household oils and harsh cleaners; they can darken or stain unevenly.

Resting it.

Store somewhere cool and dry, out of direct sun. Don't overload a wallet — keeping it to what you use daily helps it hold its shape for years.
