This is a blazer button set produced by Hardy, a long-established British fly fishing manufacturer, to commemorate its 110th anniversary. The buttons are made of solid brass by London Badge & Button Co., a manufacturer that has long been a purveyor to the British Royal Family. This is a set for a three-button single jacket. It is typical of British Hardy to handle such gentleman's accessories, despite being a fly fishing manufacturer. I am listing this item due to decluttering. Please understand that this is a used item before purchasing. Thank you.
