Good luck on your exams! This is a 0.5mm Kurutoga mechanical pencil, exclusive to the University of Tokyo. I kept it as a spare, so the case got dirty and I threw it away. Two HB pencils for academic success from Yushima Seido, the shrine of academics. Yushima Tenmangu Shrine (Tokyo): Famous as a god of learning, it is affectionately known as "Yushima Tenjin." These shrines offer special pencils as amulets believed to bring good luck in passing exams. If you are looking for pencils for academic achievement or to pray for success in your exams, these are recommended. It will be wrapped in bubble wrap and secured with cardboard for shipping. Thank you for looking.
