This is a collaboration product between Butler Verner Sails and Traveler's Factory. This pen case is made from molded natural leather. It has a simple design that closes with a rubber band, but it makes the most of the material's quality, allowing you to enjoy the aging process for a long time. It will become softer with use and will be slightly flexible, so although it's not shown in the photos, a small eraser can also fit to the right of the pens. *This listing is for the pen case only. □ Brand: Butler Verner Sails □ Collaboration: TRAVELER'S FACTORY □ Made in Japan □ Material: Leather (natural leather) □ Size: 17 x 7 cm Thank you for viewing.
