This is a Rephr brush 16. It is sold as the smallest crease brush for eye shadow placement precision. It is made of natural fibers in Japan. I bought it with other eye brushes from Rephr but I never get to use them for some reason. I hope you can see from my picture is practically brand new. In case you need more pictures please send me a message and I will add more. I am cleaning my brush collection so keep looking and maybe combine some for extra discount and free shipping. This has been washed and sterilized. Smoke free per free home. Please let me know if you have any questions.
