The creator of Glass Studio Matsubokkuri (ガラス工房まつぼっくり), Kiyoshi Matsumura (松村潔), became an independent artist of oxygen burner work + borosilicate glass in 1995 after about 10 years of training as a physics and chemistry glass craftsman. Since then, he has been creating a variety of works ranging from glass rings, pendants, wine glasses and other vessels. Then, making use of all his technical experience in the field, he started making glass pens around 2007.
Matsubokkuri glass pens are made of borosilicate glass. Glass pens other than the Triangle and Crystal series use hollow glass tubes, so their lightness is also a major feature which reduces fatigue when writing.
