Can someone tell me about ninja cord? The website does not exist anymore so there’s no way to get info. It claims to have the highest tensile strength on the market. I noticed your store no longer stocks it, is there a reason why? I bought a few rolls and would love to hear honest opinions prior to working with it. I use Opelon the most, and had some fraying issues, so hoping this cord is good as all others have failed for my needs sadly. My daughter is 10 and I make her sensory bracelets with silicone round beads. The Opelon stretches no matter how much I pre stretch it, and frays. The whole point is for my daughter to be able to pull on a bead when she needs to. One great Opelon trait is that because flat it has killer knot locking capacity. I do a surgeon’s knot, another next to it, then some weaving, and then do a few sporadic sailing knots, with flexible E6000 dabbed on final end. I’ve never had a knot slip open, but have strands fray off the Opelon and massive stretching. I detest Stretch Magic and Powercord, and have tried everything. If anyone know what Rustic Cuff uses on theirs or Tarina Tarrantino, their stretch cord has held up for years for me.
