In cooperation with The Tolkien Shop, the largest Tolkien themed store in the world located in Leiden, Holland, I've brought some of their patches state-side in what very well may be the first ever international Tolkien Patch swap.
The Helmet of Sauron. Composed primarily of silver faux leather and stitched with black thread. This patch is 3.25" tall and 2.25" wide with a cloth back.
