walnut shell
Hard seed cover
The hard outer casing of a walnut, protecting the edible kernel inside.
Walnut shells are notably tough and textured, requiring a nutcracker to open.
In a nutshell uses the walnut shell as a symbol of compact enclosure.
Crushed walnut shells serve as an abrasive in industrial polishing and cosmetic exfoliants.
