About the bridle leather used this time
The limited edition model uses bridle leather from Thomas Ware & Sons , a long-established British tannery.

Bridle leather was originally developed for use in horse tack. It is used for horse reins and saddles, so durability is of paramount importance. Finished by repeatedly applying tallow and beeswax, it is strong, holds its shape well, and can withstand daily use.
The white powder that appears on the surface, known as "bloom," is the wax seeping out. This is a unique phenomenon to bridle leather and is a sign of high-quality leather . With use, the wax blends into the leather, gradually developing a deeper luster. At first, the leather has a matte texture, but one of the joys of using it for six months or a year is watching the luster increase.

Thomas Ware & Sons was founded in 1840. Using techniques cultivated over more than 180 years of history, they continue to produce leather that is firm and crisp, yet becomes more comfortable to the touch the more it is used. This venerable tannery has even won the Queen's Award, the UK's most prestigious business award .
Available in three colors
This time we have three colors available.
black


This classic color is perfect for business situations. Enjoy the firmness of bridle leather and the lustre that increases with use. It pairs well with both suits and casual jackets, making it a versatile color for any occasion. Because it's a classic, you won't get tired of it, and it's a color you can wear for a long time.
Dark Brown


As the name suggests, it is a fairly deep brown. It has the calmness of black, making it suitable for any occasion, but also has a warmth that is different from black. It blends naturally into everyday attire as well as business settings.
Green x Hazel


This two-tone card case features green on the outside and hazel (pale brown) on the inside. The contrast of colors that can be seen when you open the case creates a subtle sense of individuality. Perfect for those who want something a little different from the norm. The color scheme is perfectly balanced so that it won't stand out in business situations.

FAQ
Q. What should I do about the bloom (white powder)?
Blooming is a phenomenon unique to bridle leather, so there is no problem if you continue to use it as is. As you handle and use it every day, it will naturally blend into the leather and develop a glossy finish. If it bothers you, wipe it dry with a soft cloth or brush it.
Q. Can I have my name engraved?
Unfortunately, the bridle leather "Through" is a limited edition product and cannot be engraved. If you would like to have your name engraved, please consider the regular version of "Through."
Q. What is the difference between the regular version of "Through"?
The regular version of Buttero leather is firm, while Bridle leather has a hard surface, but both are durable and can be used for a long time. Please choose your favorite one by looking at the texture and color. There is no difference in specifications such as shape and storage capacity.
