About the Leather Japanese Glove Leather

Made from durable and supple Japanese glove leather, known for its lightness and strength.

Originally used for baseball gloves, this leather is highly resistant to friction and becomes softer and more comfortable over time.

Its rich color comes from the deep-dyeing process, in which dye penetrates all the way to the core of the leather.

Finished with special oils for added flexibility, it offers a soft, lightweight, and resilient texture that feels naturally smooth in your hand.

Leather Products

• Natural leather is used, and features such as veins and wrinkles are part of its inherent character. Even within the same type of leather, variations in color, thickness, and texture may occur.
• Leather color may shift when exposed to moisture.
• Color coatings on certain products may fade or crack with rough handling. Because each item is handmade, the actual size may differ slightly from the listed measurements.
• Depending on your device, the products color may appear differently on screen.
• Please be careful to avoid stains or color transfer from water exposure.

Brass Products

• Due to the nature of brass, some areas may appear slightly tarnished during manufacturing.
• We use solid brass, which develops a natural patina over time. Please enjoy this aging process as part of the products character.
• If you wish to remove tarnish, you can use a silver polishing cloth. Always test first on a small, inconspicuous area.
