This material is made of titanium that has been baked and finished with a gradation of colors through heat. Please note that there may be some unevenness in the baking as it is done by an amateur. Titanium is a hard and durable material with a sense of weight, and it has been attracting attention recently. Due to its robustness, it is difficult to process and tends to be offered without finishing, but skilled craftsmen will finish it thoroughly. Can be used for personal seals, bank seals, and registered seals. A case with a vermilion ink pad is included as a service.
