These hunter emerald green satin drawstring gift bags are super easy to use. First, open the drawstring at the top of the bag. Then, you can put your items like jewelry or candies inside. The fillable area of 4' x 5.25' gives you plenty of space. When you're done filling, just pull the drawstrings to close the bag. As for maintenance, keep them in a dry place to avoid damage. If they get a little dirty, you can gently wipe them with a soft, damp cloth. Don't machine - wash them as it may damage the satin material. These bags are perfect for weddings, parties, birthdays, or any event decoration.
