The thread is strong and fine, perfect for tying small flies. It holds well under tension and splits cleanly when needed. I’ve used it for both dry flies and dubbing, and it performs consistently.

Highly satisfied with the strength and smoothness of the silk. The 18/0 size is just right for tiny patterns. The 100-meter spool is a good value for the amount of thread needed for frequent tying.

Works well for small flies, though it requires a ceramic bobbin to perform optimally. The thread doesn’t fray easily and maintains its integrity during tying.
