Beautiful mix of NBR method hair called isla and 1 pack of jz styles hair. Two rows. But 3/4 wefts oh each row that were sewn together during install which can be undone and reinstalled to your liking if needed. Wore for only 1 day due to scalp pain and was unable to handle it. Got them taken back out the next day. So brand new hair basically half off. They were toned down to a softer blonde but came Much blonder so you can wash the toner out and tone to your liking.
