GEM DICTIONARY Sanseido Editorial Department This book contains both a Japanese-English dictionary and an English-Japanese dictionary. It is 11 cm tall, 6.5 cm wide, and 2 cm thick. It's compact, making it convenient to carry around. I bought it in my student days at school, but I kept it stored without using it in class. It has a dedicated transparent case, but the top and bottom are torn. Same-day shipping is available. Returns and exchanges are not accepted after purchase.
