The reason why the online mailing of raw chestnuts is not broken may be that dry, waterproof and moisture-proof packaging materials are used to seal and package chestnuts and mail them through express delivery companies. This will keep chestnut fresh within four days and will not go bad.

In addition, the storage and transportation of raw chestnuts are usually packed in vacuum or foam boxes, which can prolong the shelf life and prevent spoilage. In the process of storage and transportation, attention should also be paid to controlling temperature and humidity to avoid adverse effects of high temperature and humid environment on raw chestnut.
