Feather ink quills are available at many retailers that also sell stationery or craft supplies, such as Barnes and Noble. Feather quills are also available from major online retailers, such as Amazon.com, or more specialized sites, such as Etsy.com.
Used for calligraphy and as a general writing tool, feather ink quills often come with ink as part of a set and can be purchased with a metal nib attached for easier use. Feather quills without metal nibs are often hand cut and treated, offering a more authentic, traditional feel to the instrument. Online availability is broad, with quills crafted in a wide variety of colors and from many kinds of feathers, both natural and artificial.
