What happens if you put leather in a freezer?

Putting leather in a freezer can cause it to become stiff and brittle due to the low temperatures, which may lead to cracking when it is removed and returned to room temperature. Additionally, moisture can accumulate on the leather's surface, potentially leading to mold or mildew if it isn’t dried properly afterward. It's generally not recommended to freeze leather items, as this can damage their texture and longevity.
