Party bags are small gift bags filled with treats and toys, typically given to guests at children's birthday parties or celebrations. They are designed to thank attendees for coming and to provide a fun takeaway. Common items found in party bags include candies, stickers, small toys, and sometimes themed items related to the party's theme, such as superheroes or princesses. These bags can vary in size and style, often matching the overall decor of the event. Parents often prepare them in advance, ensuring each guest receives a bag as they leave. Party bags are a popular tradition in many cultures, adding an extra element of joy to celebrations.
