To use these briefs, simply slip them on like you would any other underwear. They're designed to fit comfortably on your body. When it comes to care, it's best to wash them in cold water with a mild detergent. Avoid using bleach or harsh chemicals as they can damage the microfiber fabric. Hang them to dry to keep their shape and elasticity. And that's it! Enjoy the comfort and style of these briefs every day.
