The Apple Pencil Case was originally designed for the Generation 1 Apple Pencil. The case is made of leather and is described on Apple’s website:
“A beautifully crafted case for Apple Pencil made of durable leather, it’s available in colors that match other Apple accessories. It protects your Apple Pencil when you’re not using it while making a graceful statement — cleanly and precisely designed, just like Apple Pencil.”
The Apple Pencil Case has been available in a variety of colors, including: black, (PRODUCT)RED, electric blue, soft pink, midnight blue, and saddle brown.
This example is black, unopened in its original package.
