In addition to the previously sold "IP Grain Boundary Gold C Titanium" and "IP Grain Boundary Black C Titanium," we have now started selling "IP Grain Boundary Silver C Titanium."
IP grain boundary titanium, which is characterized by the unique beauty of the pattern created by irregularly overlapping small crystals, is made using "IP (ion plating)" + "grain boundary titanium," which requires advanced technology to make popular titanium HANKO. This is a high-quality titanium HANKO processed using "crystal (traditional technique)" in Sabae City, Fukui Prefecture, which accounts for 95% of the domestic production of Japanese-made eyeglass frames, which boasts the highest quality in the world.
- Titanium is excellent in all respects, including heat resistance, abrasion resistance, erosion resistance, and high strength. In particular, pure titanium, which is hypoallergenic, is a material that can be used safely by people with metal allergies.
To guarantee this pure titanium, we conduct a "composition analysis" every time to inspect and maintain the purity of the titanium. - The IP (ion plating) process developed by NASA is characterized by excellent film durability, high adhesion, and safety for the human body as evidenced by its use in medical care. In particular, for titanium HANKO that require non-allergenic properties, chemical plating or electrolytic plating cannot be used as they may contain cadmium, lead, etc.
The jet black and glittering metallic color are unique to the combination of pure titanium and IP processing. - Grain boundary crystals, a traditional and top-of-the-line technique, create beautiful patterns by irregularly overlapping small crystals. This advanced processing is carefully performed one by one in Sabae City, Fukui City, which boasts a 95% share of the domestic production of eyeglass frames and a high level of metal processing.
Your unique grain boundary titanium HANKO, no two with the same pattern.
For IP Grain Boundary C Titanium, you can choose from a total of 8 Swarovski colors, including crystal for both personal and corporate seals.
You can choose from 5 fonts for personal seals and 3 fonts for corporate seals, and prices start from 24,200 yen (for 13.5mm round sticks).
