Natural rubber latex is a particular kind of rubber that has been manufactured from the sap of the rubber tree. Rubber tree sap, or natural rubber latex, is a cloudy white liquid containing a large amount of natural rubber that can be used to manufacture various consumer products. Natural rubber latex products cannot be identified visually. Any rubber-like object could be made of natural rubber latex, or it could be made of synthetic material (including synthetic rubber). Items that are not are not stretchy may have natural rubber latex applied, similar to a paint-like coating.
