For those with thinner hair, these are perfect for adding to the other side of your extensions instead of a full weft. They keep the hair light and are super easy to install. The only annoying thing about them is the packaging, as they are split into maybe 10 strips of five tapes and they're each covered in vinyl to protect the tapes. It's nice that they're protected, but it is a little annoying to work with, and there's just so much plastic waste. I wish these were packaged a bit more like the double-sided tapes. Anyway, no complaints about the tapes themselves. They're sticky enough and I don't have any issues with slipping or anything.
