These favor boxes are made of thick, durable craft paper. The boxes, when folded, are 2 inches by 2 inches by 2 inches. These fold easily and I am very pleased with the quality. These would be great for pretty much any reason you would need or want to use treat boxes-- for happies, baby or bridal showers, birthday parties, or wedding gifts. The included tags and string make this set complete and a no brainer! Highly recommend!
