This Open Top Mailbox is perfect for holding valentine cards, candies, small gifts, baked goods, and more!  This would be adorable for a Teacher gift too! It is approximately 7-1/2" x 5-3/4" x 3-1/4" and is compatible with both the 8x12 and 12x12 mats.   https://jamielanedesigns.blogspot.com/2018/12/heart-boxes.html
