To use these briefs, simply put them on like any other underwear. They're suitable for daily wear, whether you're at work or out for a casual stroll. When it comes to care, it's best to wash them in cold water with a mild detergent. Avoid using bleach as it might damage the satin fabric. Hang them to dry instead of using a dryer to keep their shape and texture intact. With proper care, these briefs will stay in great condition for a long time.
