Lightweight and Cuttable
The best thing about these is that they're lightweight, long enough to be fun, and you can cut them if you want.  They're also fairly easy to manage (not a lot of tangling). I'm a week in to install of the 18" and I would order them again. I got these is T30 which is pretty true to color and very pretty. I'm not certain that these could be re-used.  They're not weak or fragile, but they are basically spirals that get fly-aways at the ends as opposed to a butterfly lock that is wrapped around itself and fuzzes at the bottom before it goes back up. Maybe re-use would be easier if you cut them prior to re-installation?  The 6 pack/120 strands was plenty for a big head, and it was &lt;$25.
