Reducing the price due to limited storage space. I'm selling this as I have no room to store it. I bought this when my son, who will be a university student this spring, was about one year old (it cost around 100,000 yen at the time). We stored it in a warehouse during my overseas assignment, so it was displayed in the living room for about five seasons in total. I wiped off the dust, but it's not perfectly clean. I would appreciate it if only those who understand this would purchase it. Thanks to this, my son has grown up healthy and has been accepted into a private university in Tokyo. Perhaps the effect of this kabuto (helmet) had some influence.
