This is the first model system planner from Aura Arca. The color is black, and it's a mini 6 size. The ring diameter is 19mm. I pre-ordered it at Ginza Ito-ya in October and finally received it, but I've decided to sell it because I've started using a different planner while waiting. I put it back in the box immediately after taking the photos. It has a D-ring, so you can attach your favorite charm (❁ᴗ͈ˬᴗ͈) It's a very luxurious planner. This item is currently sold out. What I'm selling: ☆ Aura Arca Eternum Mini 6 Black ☆ Aura Arca original box ☆ Dedicated micro cloth mat ☆ Logo key holder charm (unopened) ☆ Logo magnet (unopened) ☆ Ginza Ito-ya purchase certificate card The price reflects the commission, shipping, and difficulty in obtaining the item. The brand's first model, "Eternum," uses luxurious calfskin for the mini 6. Designed to be used for many years as daily records accumulate, this model embodies an aesthetic that enriches your system planner life in every detail. The ring hardware uses the largest 19mm size for a mini 6, while the width is minimal, designed to look slim. The beautiful proportions make it easy to hold and carry. The flap has a double hook. Its beautiful and charming appearance makes you excited every time you open and close it. The special 7mm diameter hook is made with a meticulous process of punching a large piece of metal and then punching it again to make it smaller. The logo engraving uses the traditional "yagen (mortar) carving" method. Because the cross-section is carved in a V-shape, the letters stand out sharply, and the clarity of the logo remains distinct even after long use. A large pocket that can hold bills is placed on the back. It can also be used as a wallet planner. You can also store A6-sized documents and tickets. The left pocket on the inside uses the "accordion gusset," a traditional leather craft technique. The high-quality leather overlapping the gusset creates a beautiful appearance that harmonizes functionality and elegance.
