there not pieces u have to measure how long u need it an cut it there's a lot left I did my hair 3 times with it an there is A LOT left its very good hair the track part is very thin so it makes blending even better its last long also VERY GOOD QUALITY HAIR u can google remy hair an ull see
yes both are remy when I had some in it last for quit a while my hair is now longer that the extensions so I no longer need them it doesn't matt up very good quality I love em
I'm sure u can I've never done it but I'm sure there is a way I've always used glue for mine but this hair is nevr been used so there's no glue on it an it last a long time
yes u get both an u can glue them with special hair glue from the local beauty supply store or u can braid ur hair back an have it sewn in but I glue mine in an when u want to take them out u get the glue removal its like a dollar
