Ballpoint pen where upside down Fuji appears How to make a sakasafuji

ESKESEN, which was born in Denmark in 1946, continues to make Floating action pen. There, I expressed the story until the phenomenon "upside-down Fuji" in which Mt. Fuji was reflected on the surface of the lake was created. When using a ballpoint pen, you can only see the clouds and the words "HAVE A GOOD DAY". If you turn it upside down, the clouds will start to move, and Mt. Fuji will come out first. Upside-down Mt. Fuji appears before the blue color flows down like melted snow. A story of only 6 seconds, fascinated by a ballpoint pen. Please look at it when you want to refresh. HAVE A GOOD DAY! * About use: You can insert and remove the pen tip by twisting the handle of the pen. Avoid writing with the pen tip facing up, and be sure to store the pen tip after use. It may cause ink leakage. Bubbles may be seen in the floating part, but this is due to the characteristics of the product and is not a defect. Do not leave it in an extremely cold or hot place. If any damage or cracks are found, discontinue use. * About core replacement: Since it is made in Denmark, the replacement core is not compatible with domestic commercial products. In addition, it is necessary to remove it with force, and the manufacturer does not recommend replacing the core by yourself. Material: ABS resin, chrome steel, PET, PP, mineral oil (vegetable mineral oil US FDA certified), 0.8mm oil-based ink Size: W143mm, H11mm Manufacture: Denmark Design: Tomohiro Ikegaya (Japan)
