A Carina 15 TS in Fubuki Koi with Nickel Silver trim and a Stainless Damasteel clip. The TS model designation points to the large TWISBI Swipe converter cartridge that will give you nearly twice the ink capacity over a standard converter. It comes with a Magna Carta #8 Steel nib and the larger TWISBI converter.
TS pens are about 5mm longer than their non-TS counterparts due to the extra length of the cartridge.
Please note that these Nibs are only available in Fine, Medium or Broad and, at least currently, only in Polished Steel, so please select from these options in the drop down menus.
