Botanical Garden Walnut Rollerball Pen
This limited edition roller ball pen was hand turned from an American Black Walnut tree (Juglans nigra) that grew for at least 40 years on the grounds of the Yale Marsh Botanical Gardens at 227 Mansfield Street. The tree was removed in 2010 to increase sunlight to the greenhouses. The heartwood is a deep chocolate brown with a contrasting white sapwood. To our knowledge this was the only walnut tree on Yale University campus.
