This is a 150-piece set of 【Moku Rock】 blocks. These blocks have the warmth of wood. I received this as a gift, but I haven't used it and it has been stored at home. I took the blocks out of the furoshiki (wrapping cloth) and arranged them for the photos, so the condition of the product is listed as "Like New." Target age: 3 years and up Product details: 150 blocks, furoshiki (wrapping cloth), plate, instruction manual Product name: Moku Rock 150-piece set Materials: Maple, Cherry, Magnolia, Birch, Hornbeam, and Zelkova (produced in Yamagata Prefecture) * 5 of these tree species are used. They vary depending on the season. Size: Approximately 1.6 x 3.2 x 1.3 cm (per block) * The blocks were taken out of the furoshiki to check the contents. * Please refrain from purchasing if you are sensitive to minor imperfections, as this is a personal inspection. * The box may have some stains due to being stored at home. Although it is unused, it has been stored at home. Thank you for your understanding.
