These white satin drawstring bags are very easy to use. First, open the drawstring at the top of the bag. You can put small items like jewelry or candies inside the bag. Once you've filled it, pull the drawstrings to close the bag. As for the use occasions, they're great for weddings, parties, birthdays, or any special event. When it comes to maintenance, keep them away from sharp objects to avoid tearing the satin. If they get dirty, you can gently wipe them with a soft, damp cloth. Don't soak them in water as it may damage the satin's texture.
