This larger set includes all 10 tips; the 5 from the # SET99X5 plus 0.4mm(1/64"); 0.8mm(1/32"); 1.2mm(3/64"); 1.5mm(1/16"); 2.0mm(5/64"); 2.3mm(3/32"); 3.0mm(1/8"); 3.9mm(5/32"); 4.7mm(3/16"); and 5.5mm(7/32") tips.
Chrome steel balls welded onto the end of the tip gives excellent heat retention (better as the ball is bigger). The polished ball ends are buttery-smooth to write and draw with. Line widths are consistent and repeatable in all directions. Our 1/64" (0.4mm) ball tip is the smallest in the world.
Will only work with the Binding-Post Interchangeable-tip Pen #BPH.
Use of heavy duty cord is recommended. Razertip's brass brush is perfect for cleaning these tips.
