If you have multiple children or want multiple books, you do not need to purchase a separate box for each book you want. You can send art for more than one kid or book in the same box separated and labeled,
Our boxes hold 300-400+ pieces of flat art, are 24x17x4, and you CAN combine different kids’ art or art for multiple books/mosaics in the same box as long as it’s separated by child/book.
There is no need to purchase more boxes than you need, as the 2nd payment you'll make is based on the number of pieces of art you send and number of books you want, NOT the number of boxes you order. Most people find that one or two boxes is more than enough to accommodate all their art.
