This is a set of two books, one about a rabbit and one about a bear. You can sweetly document your baby's life from birth to one year old. The green book has been opened once, but has not been used. The pink book is unopened. I bought them for 5060 yen, as they are 2530 yen each. You can keep a cute record of your baby's growth. They can be used for twins or siblings. Please consider purchasing them.
