Welcome to The Black Triangle Tattoo Co. We are located on Main Street in Longmont, Colorado. Established in 2015, we have two Artists participating only in custom and unique tattoo designs. Click the portfolio page for a good look at some of the work we have done. You will leave the shop knowing your tattoo was tailored exactly to your own expression and vision. The graphite page is displaying actual 'piles' of ready-to-tattoo-drawings, they will only be tattooed once and then put away forever. Set an appointment by email or phone from the contact page. Also, feel free to message us with any questions you have. Thanks so much for visiting!!
