We love our photo frame decorations because the so capture the moment in the Baby's life! The size of the opening is just right for an infant's picture, the one they take in the hospital. Or if your baby is older now, put in a photo you actually take on his First Christmas so it will be a treasured memory forever! The frame is made of polymer clay, a very durable material. It has a black mat board backing which opens up to receive a photo. There is a stand on the back so this little personalized ornament gift can be used all year long, standing on your dresser to remind you of your cute baby boy.4 3/4" X 3"
