Mini 6 size Limited 20mm Black If you are paying at a convenience store, please comment first (due to many cancellations). I won the online lottery in July 2025 and purchased it. I only opened it for photography and have never used it. (I did check to make sure there were no problems with opening and closing the rings) Normally 13mm, so 20mm rings are very valuable. I want to sell it to someone who understands this value. I also own a 13mm black one, but it's the king of system notebooks, and the aura is different! The leather also "sings," and the appearance is different. It's leather that ages beautifully. Since this is 20mm, you can probably consolidate everything. The Authen has a rounded shape, and there's still room even when you close the refills, so you can also put in notebooks. Many people put in the Nou-ritu Techo Gold. Please pack a lot of information into a cute, compact system notebook (❁ᴗ͈ˬᴗ͈) Because the color is dark, the leather's natural markings are less noticeable than other colors, and it's very beautiful. If you don't like leather scratches or unevenness, black is recommended without hesitation. ※Instant purchase OK ※No returns due to the prevention of switching 【Product Details】※Quoted from the official website below The "AUTHEN" series, which bears the name "AUTHENTIC." It's a series that gives you a somewhat nostalgic feel the moment you hold it in your hand. This is a combination of European tanner leather, made from the finest French raw hides, using high-quality shoulder parts that have been tanned with 100% vegetable tannins over time, and Tokyo's traditional pigskin (pig leather), which is also finished with full-tanning, with original processing by Japanese sewing craftsmen, creating a unique material. The flap type uses a 100-year-old, purely domestic high-quality hook that continues to be particular about springiness. You can enjoy the sound of the leather and the feel of the hook spring every time you use it. Because the leather is maintained by its own oil content, there is no need for maintenance, and it's a series where you can enjoy deep flavor and luster just by using it, as well as natural aging.
