The illustrations are easy for young children to understand. This book selects 200 words that toddlers in America learn first. Paired words like "high/low" are presented on facing pages, making them easy to remember. Stored in the warehouse as-is, in the original packaging. This is a single set for sale, but there are 10 sets in stock. If you would like to purchase 3 or more sets, please comment first. I will create a dedicated page for you. For 3 or more sets, shipping will be via courier service (60 size or larger), but the price will be 750 yen per set plus shipping. I will not respond to requests for price reductions. Please understand that I will ignore such comments due to being busy.
