I wanted to try the marly twist for a while now and I finally got them. I had my aunt install them. This was pretty new to the both of us but we wanted to get the twist right even if it took a couple of times. So, I bought five packs of marly hair from my local beauty supply store. The pack are like $4.99 a piece. They come in sperate pieces so all we had to do is thicken up each piece. They are all different lengths and sizes. There not perfect since this was new to us. They are kind of heavy and unravel at the bottom but other than that they are gawwwgeous lol.
