A growth album that can record heights from 70cm to 135cm. Unopened and unused. It seems you can measure height, put photos in the album, and record and display it on the wall. I received it as a gift, but I missed the chance to use it. Perfect for children or grandchildren. - Product Name: Height Record - Design: Acorn Village - Country of Manufacture: Japan - Target Age: 0 to 7 years old - Size: Records heights from 70cm to 135cm - Features: Growth record album Thank you for looking.
