Charming Pen
"I love everything about Tsukuyomi. It was wonderfully made and true to nib size (mine is fine)."












Tsukuyomi is the moon god in Japanese mythology and is revered as the god who rules the night. This glass pen was created by glass artisan Rika to dedicate to Tsukuyomi.
Inside the glass pen is an opal floating on a series of pillars, designed with the concept of enclosing a gemstone crystallized by the light of the moon. The surface of the glass pen is sprayed with silver to further emphasize the fantastic atmosphere. Each stroke of this pen is not merely writing but an act of devotion to the moon's serene beauty.
The appeal of her work lies not just in its beautiful design and concept. Her pen nibs are incredibly smooth, almost eliminating any dragging sensation. This is one of the reasons why many fans of Japanese glass pens are avid supporters of her creations.
We also want you to know her not only as an artisan but also as a person. Please look at 'The Story of SOURIRE' below and feel her charm.

After graduating from an art university, Rika Suga began creating glass artworks in 2004. Her creations, born from a unique sensibility, encapsulate a romantic worldview. Her cheerful and approachable nature adds to her charm in contrast to her focused demeanor during production.

SOURIRE, which means 'smile' in French, captures the essence of Rika Suga's atelier in the heart of Japan in Shinshu Azumino. Surrounded by the Japanese Alps, the atelier offers serene views of Mt. Ariake. Rika draws inspiration from the ever-changing scenes of the mountains, the clarity of the air, and the purity of flowing waters, creating pieces that aim to bring a smile to those who encounter them.

Her craftsmanship is also exceptional, particularly noticeable in the smooth glide of the pen nib. Japanese glass pens are often of high quality, offering a smooth writing experience with minimal drag, but her creations are particularly notable for their exceptional smoothness.

"I love everything about Tsukuyomi. It was wonderfully made and true to nib size (mine is fine)."
"Such a beautiful work of art, and highly functional as well. I can write around half a page, edge to edge, on A5 paper. Sometimes a little less or more depending on the ink. The fine point is perfect thickness for writing in dot grid A5. However, because it's fine point, it doesn't show off dual-shading/sheening inks as well as a broader nib. I really love the way the center design catches the light. I'll often just stop and look at it while I'm writing."
"I am positively floored with my purchase experience through KOMOREBI, not only in first hand acknowledgement I made the right choice in glass dip pen with the Sourire Tsukuyomi in green (even more vibrant in-hand, glides oh so smoothly, and the silver spray adds a bit of a secure friction to aid grip), but in my glee at the quite special Furoshiki unboxing experience. Taka and Sayuri take a rare and genuinely loving approach to safely deliver products they clearly value, all safely packaged and ready to greet you with a hug. I will cherish my new pen and inks, and my Furushiki will be put to good use within my travel sketch kit. Thanks you so much for making my week!"
"Received my second glass pen from this lovely company. The nib is very sharp and its glows a beautiful green. I love to paint the sea and it reminds me of seaweed. Thank you for my piece of art - I will treasure it! Great support and shipping."
"I purchased this glass dip pen with my second order. Unlike the other glass pens that were very delicate, this one has nice heft to it. The pen itself reminds me of an icicle, but also has a completely different texture in the center of the body. I can’t stop touching it! Rika-san’s lamp work skills are very unique. The photo does not do justice to the beautiful floating opal."
