Human hair clip in extensions

I bought these extensions 2 years ago and wore them a total of 5 times. They are real human hair extensions from Luxy. They should be 20 in 220g in the color Dark Brown. You can curl,straighten and dye them with no problem at all. I am very blonde now and my hair stylist said it would be better to sell them than bleach them and ruin the integrity of the hair. Very clean, non smoking home, basically brand new still. 4- 1 clip extensions 2- 2 clip extensions 2- 3 clip extensions 2- 4 clip extensions
