The Wood Glass Pen Premium Twin Gift WGP-4TW_GIFT (Bordeaux) from the Glass Pen Studio Kasyo.

From Glass Pen Studio Kasyo, the Wood Glass Pen Premium Twin Gift WGP-4TW_GIFT (Bordeaux). ■WGP-4 Wood Glass Pen Premium Black (Glass pen with wooden barrel/Bordeaux) 【Commitment to Quality】 A hard glass nib is fitted into Studio Kasyo's original wooden pen barrel. The wooden barrel makes the pen sturdy, comfortable to hold, and exceptionally lightweight. The glass nib can be detached by twisting and pulling, allowing for easy replacement. ■How to Use Your Glass Pen Please use water-based fountain pen ink in bottles. Dip the nib about halfway into the ink and then lift it out. The ink will be drawn up into the grooves of the nib through capillary action. You can then write characters and lines with the ink that has ascended into the grooves. The nib has 10 grooves; by occasionally rotating the pen as you write, you can evenly utilize the ink within these grooves. The hard glass nib is very delicate. Applying pressure to the rim or bottom of the ink bottle can cause breakage, so please be cautious. ■How to Care for Your Glass Pen After use, rinse the ink off the nib with water. Gently dry it with a soft cloth and store it with the nib cover attached. If ink becomes stuck in the nib's grooves, gently clean it with a toothbrush under lukewarm water. ■Due to the nature of burner work, the shape and line width of each glass nib are completely handmade, resulting in slight individual variations. ■If the nib becomes damaged or worn, please replace it with a separately sold spare nib. Spare nibs are available in four line widths: EF, F, M, and B. To purchase replacement nibs for the Wood Glass Pen, please inquire at the store where you purchased the pen or contact Studio Kasyo directly. The hard glass nib of this product is detachable and has a sharp tip. To prevent accidental ingestion or injury, please ensure it is used and stored out of the reach of children. 【Product Specifications】 Glass Pen ■WGP-4 Specifications Total Length: Approx. 150mm Weight: Approx. 9g Nib: Hard glass (Fine point) Barrel: Wood (Bordeaux) Maximum Barrel Diameter: Approx.
