This is a Rhodia pen holder. The size is NARROW, and the color is orange. About the product: https://www.shop.quovadis.co.jp/SHOP/1691.html?srsltid=AfmBOopxfKQjGenG45HIcQFYBJfFrhW6uxHADzpgeRo1v8R7SO1YyFd0 It's a pen holder that attaches to notebooks and planners, and can be adjusted with rubber and Velcro. This is the NARROW version, which holds one pen. Size: 20x430mm Material: Synthetic leather and rubber Specifications: Holds one pen up to 11mm in diameter. I bought both the WIDE version (for two pens) and this NARROW version, and I don't think I'll use this one, so I'd like to sell it. I opened it once and attached it to a planner, but it didn't fit, so it's unused. However, the cardboard packaging from when I bought it is for the WIDE version. I accidentally threw away the NARROW packaging, so I will send it in the WIDE packaging. Therefore, the photo shows the WIDE version, but it is the NARROW version that holds one pen. Please be aware of this. For those who use Rhodia, Hobonichi Techo, Rollbahn, Quo Vadis, Traveler's Notebooks, or other planners and diaries, or for those who love stationery, how about it? The retail price is 1650 yen. I will sell it at a lower price. Thank you.
