1. Do not wash with water; avoid prolonged folding or heavy pressure.
2. Store in a well-ventilated, dry place. When airing them out, dry them in a semi-shaded area rather than in direct, harsh sunlight.
3. If using mothballs or other insect repellents, wrap them in gauze or tissue paper; ensure they do not come into direct contact with the wool lining.
4. For minor stains on the wool lining, gently wipe the area with a clean towel dampened with a volatile dry-cleaning agent, then air-dry promptly.
5. To remove dust, choose a sunny day and gently tap the wool surface outdoors with a small wooden stick; a small vacuum cleaner may be used if necessary.
6. For routine maintenance, gently brush the wool surface with a comb and a hairdryer to keep it soft and natural.
