Natural Latex is obtained from the sap of certain plants and can be later vulcanized and finished into a variety of products.

About Slippers:
Slippers are a type of footwear that is soft and lightweight and can be slipped on and off easily. Slippers are made out of materials such as felt, terrycloth or soft leather, and may or may not be lined. Slippers have thin and flexible soles, with a shallow tread meant only to prevent the wearer from slipping on smooth floors. Most slippers are intended for indoor wear only.
