All of Generation A T-Tech needle cartridges have a newly designed and patented protective barrier membrane and are equipped with a patented capillary-action tip that guarantees a smoother ink flow for longer periods of time.

The bugpin round liner configurations are available with 3, 5 and 7 needle points. T-Tech bugpin round liners are configured in a perfectly round shape and are manufactured with long tapers to keep some tightness between the needle points. These liners are #10 (0.30mm) in diameter and have long tapers (4mm). Bugpin liners are used a lot for lining, fine detailing, dot work, and filling out details.
