New, Unused SEASAR GRAVIUM Practical MAX Mechanical Pencil Seasar, who has reviewed numerous writing instruments, has spent two years developing this mechanical pencil with the theme of "Practical MAX." It achieves a fusion of opposing characteristics: "heavy yet writes lightly." The 37g heavyweight body incorporates a 13g brass weight, designed for optimal weight distribution. The pen's own weight naturally assists with writing pressure, providing a light and comfortable writing feel the less force you apply. The body surface uses a soft-feel coating called "Neo-Lavasan." It features a smooth, pleasant texture and excellent grip. The clip can be easily attached and detached by simply turning the top cap. Removing the clip reduces the moment of inertia, allowing for even lighter writing. An O-ring is installed to suppress minute vibrations and play during writing, providing a high-quality writing experience. ・Made in Japan ・Lead Diameter: 0.5mm only ・Color: Black only ・Weight: 37g ・Total Length: 140mm ・Maximum Diameter: 11.3mm ・Center of Gravity (with clip): 69mm from the tip ・Center of Gravity (without clip): 66mm from the tip (easier to write with) ・Guide Pipe: 3mm (fixed) ・Chuck: Metal chuck (no cushioning function) ・Clip: Detachable (original clip with dedicated mold) ・Eraser: No cleaner pin ■Materials ・Weight: Brass, glued and fixed to the shaft ・12-sided body: Aluminum (Neo-Lavasan coating) ・Clip: Iron ・Top Cap: Brass ・Knock Cap: Brass ・Lead Tank: Resin
