100% Human Hair Clip In Hair Extensions Brown Blonde Balayage 16”

Another impulse purchase. I bought these, opened the package and realized I have no idea how to use these clip in hair extensions, so I never tried them out and put them back in my closet until today. They are 100% human hair in brown/blonde balayage style, between approx. 16"-17" long, and contain 8 pieces. All measurements are approximate: 2 pieces x 7.5" wide 2 pieces x 5.5" wide 2 pieces x 3.5" wide 2 pieces x 2" wide Please ask me questions - I don't know anything about extensions so don't know what is important to know about them. Comes from a smoke-free, scent-free home. Shipping will be same day or, if ordered after 3pm ET, the next day.
