First, let me just say that the SFX line of brushes are AMAZING and I am in LOVE!
As always with Bdellium Tools, the quality of this brush is amazing. I personally found this brush to be a little thick for creating capillaries but it could be just my technique since I'm new to SFX, but I found that I was perfect for creating main veins and detail work that's just a touch bigger than capillaries (again, I just may need practice!). I used it for a full month, two of those weeks were for Halloween looks and I feel like these SFX brushes were perfect for all the looks I did. I highly recommend these SFX brushes!!
