The central idea

Walnuts are natural fruit rather than uniform manufactured objects. The source of a mark, the extent of any intervention and its effect on structure matter more than simply whether a blemish exists. Distinguish natural traces, limited disclosed repairs and serious damage. Ask to see each known issue before deciding whether it is acceptable to you.
