Is it fast and supposed to be loose? WD-40.

Is it loose and supposed to be fast? Duct tape.

The idea that surprised me the most was the arrow fletching.

Absent survival conditions, I used it in a bout of boredom to neatly wrap a normal tobacco pouch (to cover ugly warnings, also helps avoid confusion when many pouches of the same popular brand are on the table). Have had it for more than half a year, carried it around in my jeans pockets all the time and I'm still impressed how little wear and tear has occurred so far, except two corners where I effed up the seam myself due to lack of experience. I completely crumpled it up into a ball once to throw it at someone, and it never lost its shape. Wonderful stuff.
