A memorial album for recording a baby's growth, allowing you to easily create handprints and footprints. Apply the included developing solution to the hands and feet, and press them onto the included handprint paper to capture the prints. There are instructions for how to use it well, so it should be easy to understand. (Be careful not to let the paper be touched by the hands of the parent who did the work, as the solution will develop when it touches the paper.) There are two sets, so how about for twins or siblings? Album size: Approximately 27.0 cm tall Approximately 24.4 cm wide If you have any other questions, please feel free to comment.
