Nichigan's "The Bears' School" I Love Ototsumiki Wooden Building Block Set (Balance & Shape Play) Recommended for 10 months and up These building blocks have a pleasant sound, not like a bell, but like small wooden beads rolling around. My child loved them and used them, developing their play, until they were about 3 years old. All parts are present. Wooden box frame included. Original packaging box not included. Alcohol-sterilized. There are no major chips or cracks, and they are still usable, but please understand that these are used items that have been played with by a child.
