This is the "Timaze" fountain pen "TTi-110 Titanium Blue," which was sold through crowdfunding. At the time of sale, it was available in aluminum, brass, copper, and titanium, each with a matte and mirror finish. This is the titanium mirror-finish blue version. The blue color was exclusive to the titanium version, with the nib also finished in the same color as the body. It was the highest-priced model in the series, and this color is already difficult to obtain. The main feature is its unique bamboo-inspired form. Five "knots" are carved into the body, cleverly camouflaging the seams of the cap and ink space. The unified aesthetic gives the impression of holding a single bamboo stalk. The titanium blue has a mirror finish, combining the coolness of metal with the warmth that conforms to the skin, creating a beautiful luster and a tactile feel that adheres to the fingers. The material is lightweight and highly durable titanium. However, it doesn't feel too light like the aluminum version; the weight feels just right in the hand, making it comfortable for long writing sessions. The pen features a German-made SCHMIDT F nib. Its smooth ink flow and stable writing performance are attractive, making it suitable for a wide range of uses, such as letters, notes, and sketches. The ink supply is a converter type with a European standard. It is compatible with both cartridges and the piston-filling method, offering a high degree of freedom in ink selection, which is a nice feature. The Timaze TTi-110 is a fountain pen that allows you to feel the "joy of using" with its combination of design, functionality, and material beauty. The fusion of the organic beauty of bamboo and the futuristic feel of titanium makes it a unique writing instrument that stands out from the crowd. The titanium blue, in particular, is a one-of-a-kind masterpiece.
