The 0.25 mm thread slides through seed beads without splitting, which my old spool never managed. I've used maybe a third of the 50 meters already and nothing has snapped on me yet.

I strung three necklaces with this and the 50-metre spool barely lost any length. It's strong enough to pull tight without snapping, though I did have to double-knot it since it's so slick.

That 0.25mm invisibility is no joke — I strung a whole bracelet and you genuinely can't see the thread between the beads. Knots hold tight too, no slipping so far.
