Dried tropical fruit called as Luffa from the cucumber family. Conventionally used for cleaning and exfoliating your skin after bath. Cut it into smaller pieces to replace your sponge in washing your dishes.
This tool can withstand the test of time by simply drying it out every after use. Avoid letting it overstay in a wet area. If used in a daily basis, occasionally microwave it for 20 seconds when damp.
