I use it in every tattoo cover!
This is a really well thought out brush design, I can get into tight spaces like around the tear ducts and nostrils for very precise stippling. That makes it my go to for black eyes, and capillaries. This brush is also really great for Stippling the edges to blend them out around tattoo covers, whether you using a PAX or an alcohol palette. It's great for breaking up the edges so my coverage area doesn't end up creeping out too far past the actual tattoo. I bought one on the advice of a friend some time ago but just ordered 5 more because I use it constantly :)
