A wedding card box serves as a decorative container placed on the gift or welcome table at a wedding reception. It provides a safe and secure location for guests to leave greeting cards, gift cards, checks, and monetary gifts for the couple. There are various styles of card boxes available, such as acrylic, wood, glass, metal, and vintage-inspired designs. These boxes are often complemented with a Cards & Gifts sign to help guests easily locate where to place their cards.
