Glass Studio Kasho Rokkaku Jiku (Hexagonal Shaft) Chopi Hana Glass Pen Both are easy to write with and have no scratching. Fine nib. The writing experience was very good, but the hexagonal shaft didn't fit my hand, so I'm selling it. The Chopi Hana glass pen also has a good writing feel, but there is ink residue... It remains in almost all the grooves, and it has hardened, so please try to remove it with lukewarm water or a soft toothbrush. Currently, there were no problems with ink retention or use. I'm selling them as a set to organize my belongings. I think it would cost around 10,000 yen if you bought them separately. The box has some damage. Please understand that these are used items.
