“These fit the tape tabs perfectly. I apply the tape to the tab then take the white pieces off when applying to the hair. I also found a flat iron on low (200-250) tapped onto the sandwhiched tabs helps bind everything together really well. 1 pack of extensions (20 pieces) should last 6-8 months. So I buy 1 pack of tape per pack of extensions and it lasts the lifetime of the extensions. When the tape runs out its time to retire the hair and buy new.”
