Sekisei Azone Silicone Glass Pen, Onion Shape

The combination of glass and silicone creates a new and innovative glass pen experience. The soft, flexible silicone material makes it easy to grip and lightweight, allowing for light writing. The nib is detachable, so it can be easily replaced if damaged. Replacing the nib is as easy as pulling it out of the barrel.
*A new sensation of drawing: "Glass pen with silicone barrel"
*Since each glass pen tip is handmade, there may be individual differences in the degree of twist and size.
*If the glass is rough and the ink tends to smudge, please refer to the instruction manual and use the included sandpaper to adjust the texture. (Please be careful not to sand the spiral grooves.)
*This product is made of delicate glass, so please be careful not to drop it or subject it to shock. We cannot repair it if it is damaged. Thank you for your understanding.
