The oak handle is certified responsibly forested, and the goat hair bristles come from a chain of reliable suppliers.
Do not get brush wet. Do not wash with soap and water. Store in a dry place.
To clean, sprinkle bristles with clay or cornstarch. Massage into bristles gently and then shake out all powder. Repeat weekly to absorb and remove dirt + oil.
The handle can be re-oiled as needed.
Minimal bristle shedding is normal for first use.
