Seal the sea cucumber with a plastic bag, and exhaust the air in the bag as much as possible. If possible, use a home vacuum machine to clean it.

Put the sealed sea cucumber in the frozen layer of the refrigerator to ensure that it will not go bad for two to three years.

There is no water vapor in the frozen layer of refrigerator, which is the best drying area and suitable for storing sea cucumbers.

This sealed gift box is not necessarily sealed tightly, so it is better to remove it.

Reminder: the box or bag brought by the manufacturer must be removed, and the factory packaging may not be sealed perfectly. You must re-seal and package it yourself.
