Such an amazing experience! Sany and Mariel are both such sweet people! Super easy booking, easy to find, great atmosphere! Would give it 10 stars if I could. Wish I was from the area because I would definitely have a lot more tattoos done here!

I had my first tattoo done by artist Sany. She made the process really easy with great communication and giving me all the information pre and post session. Mono Moon is a beautiful clean studio. I felt very comfortable the whole process. I was able to park in a parking garage down the street. Want completed my tattoo in one session and offered me breaks and snacks if I needed. I absolutely love how my tattoo turned out, her work is so beautiful and she made my concept come to life. Healing went very well and took about 3-4 weeks.
