Standard 20mm replacement T-nibs designed for a wide range of jumbo markers. 

Is your favorite markers nib starting to get worn out from repeated use? Switch it out for a brand new one with the 20mm Replacement Marker Nibs and have it writing smooth, crispy lines just like the day you got it. 

* PLEASE NOTE this nib has a 15mm base that fits in 15mm markers like the OTR Painter, the OTR Calligraffiti, the Montana Black acrylic 15mm, and similar style markers that can take a 15mm nib. This nib produces a slightly wider, and larger line which makes it perfect for bolder tags, or any job where jumbo line work is involved.
