I am making these now and this one is for sale at a discount because I have used it a bit. It is nylon twine in black and hi-viz yellow. Folded length 30 inches, finger loop is a flat braid spliced back into the cord. Release cord is tapered from 8 strands to 4. You can see the pattern, I would call it a mirrored birds eye.
The pouch size is good for small glandes up to golf balls. It's in like-new shape. One of a kind, as far as I know no one else is using the technique I am to get these patterns (tutorial coming soon, I promise!)
Would like to get $50 for this. I can do custom lengths and patterns for $70 (it's a quite time consuming method) and I can use other materials as well. I have a couple more one-offs I will be posting soon.
