Zystal Skin Weft

Hi! This is my first post and I was hoping I could get some opinions/advice.

I was looking into ordering Zystal Skin Weft extensions and I was wondering what people thought about them or if they had any experience with the brand. I can't find much on them, but they seem like they might be good quality.

^^Thats about the only opinion I've seen on them and it's not very thorough at that.
