Unused: Seifu Suga (the previous generation) "Daimonji" Blue

I believe this is a "Daimonji" (large character) pen by the previous generation of Seifu Kan.
As it is an old item, I hope it goes to someone who understands its value.
It has never been used and has no chips.

In terms of size, I believe it corresponds to the current Daimonji, but please check the scale in the photos before purchasing.

I have several works by the previous generation, but I have a favorite, easy-to-write pen that I use, so this one is unused.
I don't think you can easily find a glass pen by the previous generation with this much thickness anymore.

I hope someone looking for one will consider it.

The seventh photo shows the pens currently made and sold by the second-generation Seiryu Kan, who has taken over. Even those are priced similarly, so I have set the price a little higher.
