These little gems are perfect for facial applications, and make an excellent sponge for liquid makeup too! Care for the sponges: Just rinse and let dry after using. If needed, wash your sponges in hot soapy water (no bleach) rinse with clean water, and then let set to air dry. Natural sponges are hypoallergenic, need very little care, and will last for years if taken care of properly. As sponges are naturally occurring & are harvested, their shapes & sizes will vary.
