walnut shells
Hard seed coverings
Walnut shells are the hard outer casings that enclose walnut meat.
Once cracked and emptied, they find various uses—as abrasive material for polishing and blasting, as biodegradable filler in cosmetics, or crushed for garden mulch.
The half-shells make natural craft materials: The children made tiny boats from walnut shells.
