The central idea

Start by checking the walnuts themselves, then clean their surfaces. Early care emphasises brushing; later care combines clean-hand handling and brushing. Do not force colour with oil or aggressive polishing. A sound, mature foundation matters more than a supposedly magical technique, and genuine changes need time rather than a fixed deadline. Inspect the received pair against the confirmed photos and video before handling it. Then clean gently, let the surface dry and begin patient brushing. The brand does not recommend oil, gloves or steel brushes as shortcuts. Keep purchase records and report any discrepancy or damage promptly. Initial brushing is preparation through cleaning, not polishing. Remove surface residue, dust and material caught in the grooves before focusing on handling. The purpose is to reveal and maintain the natural surface. Work patiently with appropriate brushes instead of manufacturing instant brightness.
