* Heat: Leather is also sensitive to heat. Excessive heat can cause the leather to dry out, crack, and become brittle.
* Sunlight: Sunlight can cause the leather to fade and become discoloured.
* Chemicals: Leather is also sensitive to certain chemicals, such as alcohol, solvents, and cleaning agents. These chemicals can damage the leather and cause it to become discoloured, stiff, and brittle.
* Abrasion: Leather is also susceptible to abrasion, which can occur when it is rubbed against other surfaces. This can cause the leather to become scuffed, scratched, and worn.
