Superior Titanium-Coated Topstitich Needles - #70/10 Pack of 5. Recommended for medium weight threads. Superior recommends this needle for use with The Bottom Line.
Titanium-coated needles have been available for longarm and industrial machines for many years but these are the first titanium-coated Topstitch style needles made for home machines.
Superior has partnered with Organ Needle Company (Japan) to bring the latest technology of titanium-coated needles to the Topstitch and Microtex style for home machines. Because these titanium-coated needles have an ultra thin coat of titanium nitride, they will stay sharper longer and outlast any current Topstitch or Microtex needle on the market. Superior Threads Topstitch needles last 5-8 times longer than regular needles.
