Ball Stylus (Series 99)Ball Stylus Tips (Series 99; 0.4mm-2.3mm) 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" ball tip is the smallest in the world.
Ball Stylus Tips (Series 99; 3.0mm-5.5mm) Nickel-plated brass balls with tip wire passing through the center of the ball gives very uniform heat. These tips take a while to heat up (the 5.5mm ball may take up to 90 seconds), but they hold their heat very well and are a joy to use. Great for writing thicker lines as well as shading and dimpling backgrounds.
