The Wingback Pen Sleeve is made from the same quality materials that make up our leather range. Cut from full-grain, vegetable-tanned Tuscan leather, it has been designed to provide an extra layer of protection for your Mechanical Pen. With each one made to order and hand-stitched in our London workshop, the leather and thread can be customised to perfectly complement your Wingback collection. Keep it classic with Chestnut leather and brown thread. Or make a statement with Charcoal and yellow.
