After watching few reviews of these dupes, I decided to give them a go. I buy them on Ebay and paid around 11$ with shipping, they arrived within 15 days.
Honestly I bought them because they are so beautiful, and they look nice in my blog pictures. But I was really surprised when I received them. They are good quality brushes, In the first impression, they look identical to original and feel very soft. I have not washed them yet and I highly recommend washing brushes before use.
I will review them in few weeks, you will also see these brushes in my blog pictures.
