These extensions are absolutely amazing, I honestly regret not buying the sooner. I used tapes for awhile from another supplier and had nothing but problems but these butterfly wefts you cant even tell you've got them in, they are light weight and so easy to wear, and the quality is amazing. I keep mine in for 4 plus months at a time and get them tightened every 10 weeks, I've had my first set of extensions for just over a year now and the hair quality it amazing, still haven't had to cut them since they were put in and the hair still feels amazing. Honestly couldn't speak highly enough of them, excited to try out the new invisi butterfly weft.
