This is a brand new, unused item. It's being sold to clear out my collection. Unlike fountain pens, this glass pen is easy to handle because the ink washes off easily with water. You can enjoy various inks with ease. It comes with a cap to protect the nib, making it convenient to carry around. The elegant curves create a beautiful marble color. It comes in a dedicated box, making it perfect for gifts. Features: ● Handmade hard glass nib ● Cap for convenient portability ● Compatible with water-based dye, pigment, and glitter inks ● Parts can be disassembled and washed with water ● Comes with a dedicated box, perfect for gifts How to Use the Glass Pen: 【1. Applying Ink】 Apply ink to the nib. If there's too much ink, remove the excess with tissue paper before use. 【2. Writing on Paper】 Write with the glass pen slightly tilted, not upright. Rotating the pen shaft little by little while writing will keep the ink flow consistent, allowing you to write more characters at once. 【3. Cleaning】 After use, wash the nib in a container of water and wipe off the water with tissue paper. If ink or glitter particles remain in the grooves, gently wash them with a brush with fine bristles. Materials: ● Nib: Hard glass ● Pen shaft: Acrylic resin ● Nib connector: ABS resin The nib is made of hard glass, which is excellent in durability, heat resistance, and abrasion resistance. #Guitar Glass Pen
