Review (5/5): Good Elastic Cord For Masks, Overall It's a great deal
It arrived fast and the cord's elasticity and memory have been similar to common respirator or surgical masks. Cuts easy, and works well so far. The only downside was that, while wound up and tied off, it was a bit tangled to get started. A small roll would be better for this, but that falls short of outweighing the good quality. I'd buy it again.
