"The Clear-Glide bobbins performed well in all three machines. Results were impressive. In all our tests the Clear-Glide performed as good or better than the other brands we used in our tests. We encountered no problems what-so-ever using the Clear-Glide bobbins in any of our machines.
The Clear-Glides were smooth running and tension proved to be adequately consistent throughout. We noticed no lint build-up in our bobbin cases from using the Clear-Glide bobbins.
While our tests were only conducted on the machines mentioned above, we have no reason to believe results would be any different on other machines. The Clear-Glide is a high quality bobbin that should perform well in any machine using the Class L bobbin."
Clear-Glide is a high-tenacity polyester filament bobbin wound on a plastic flange spool. Designed for today’s home sewing (drop-in) bobbin cases.
Clear Glide is wound on a plastic sided bobbin shell. Because of this it is not affected by humidity or oils. It is responsive to machine thread sensors so you don't have to worry about your yardage.
Clear-Glide offers more stitches or yards per bobbin than both competitive and machine wound bobbins.
