Safe Tattoo Ink
Fourteen Years Before
Anyone Asked
Is Killer Silver Ink safe? Yes. Killer Silver 7, the safe tattoo ink used at Killer Silver Tattoo Studio in Scarsdale, NY, was lab-tested in Germany for cancer-causing chemicals and heavy metals, and none were detected. It's MoCRA registered in the U.S. and has been REACH certified since 2013.
In 2012, Caesar sent his own ink to Germany to try to prove it wasn't safe. Not because a regulator asked, and not because anyone made him check.
Why? Not because he was bored, and not because he had something to prove. Caesar needed a clear conscience — certainty that the ink going into his clients' skin wouldn't cause them short-term reactions or long-term harm.
REACH is the European Union's law for chemical safety. In plain terms: it sets legal limits on how much of a hazardous substance — carcinogens (cancer-causing chemicals), a heavy metal, a banned dye — is allowed in a product before it's considered unsafe. REACH doesn't test anything itself; independent labs do that on its behalf, then hand over a certificate if a formula passes. For tattoo ink specifically, the most credible of those labs in Europe is CTL, based in Bielefeld, Germany — but CTL is just a lab. All it does is test a formula against the limits REACH sets and report back pass or fail.
The first submission failed. Caesar went back, reformulated, and resubmitted. In 2013, the reformulated Se7en Deadly Shades system — six black gray-wash shades plus the white ink used to build them — passed together, screened against the same hazard categories REACH would later regulate by law: aromatic amines, restricted dyestuffs, heavy metals, and carcinogens. Nobody in the United States was asking for that kind of proof yet. Nobody in the United States even had a framework to ask for it.
Safe Tattoo Ink: Registered isn't tested
The U.S. didn't get its first federal tattoo-ink framework until December 2022, when MoCRA was signed into law — nine years after that independent lab had already certified both Killer Silver 7 shades against those same hazard categories.
Even now, in 2026, under Robert F. Kennedy Jr. — the U.S. Secretary of Health and Human Services (HHS), the federal department that oversees the FDA — pushing for tighter oversight, the agency still hasn't finalized binding manufacturing rules.
MoCRA today means a registered facility and a self-declared ingredient list — the manufacturer's own word, filed with the government, not independently tested by a lab with nothing to gain either way. It's reactive by design: the FDA responds after complaints accumulate. REACH is proactive by design: an outside lab tests the bottle before it ever reaches a client's skin.
Killer Silver has operated under this standard since 2013 — voluntarily, for Caesar's own peace of mind as a human being, not because anyone required it. MoCRA registration, accepted for Killer Silver Ltd. in July 2026, is simply the U.S. catching up to where the formula already stood.

Inside the factory floor
Caesar spent his last dollars building a small-batch manufacturing facility in Westchester County, NY, in 2014, so he could control every step of production himself — honest on the label, accountable in his own life if anything ever went wrong.
One man, every department
"A factory" isn't one job. It's dozens, all currently running under one name:
The market doesn't care
Conscious and honest manufacturing makes a lot of sense. It just doesn't make enough dollars.
Killer Silver Ltd. is still a one-man company today, in 2026. Caesar spends his mornings at the manufacturing facility trying to make it profitable, then tattoos five days a week after that.
Fourteen years later, that's still the hole — financially. But client safety was never optional for Killer Silver, and never because an authority told it to be.
As a 67-year-old, I wasn’t sure what to expect walking into a studio, but Caesar immediately made me feel at home. I never felt out of place; instead, I knew instantly I was in the right hands. He is a true professional who treats his clients with immense respect.
I came to Caesar with a very meaningful design—a fine-line dragon and angel wing composition with a personal letter 'D' at the center. This piece was incredibly special as my sister, who recently passed away, saw the sketch and loved it before she went. Caesar handled the emotional weight of this memorial tattoo with such professionalism and grace.
His technical skill is top-tier. He perfectly captured the intricate details of the design and was incredibly helpful with placement on my inner forearm to ensure the lines flowed naturally. The shop is spotless, and his use of high-quality film aftercare makes the healing process simple and worry-free.
Although Caesar is renowned across the New York Metro Area for his expertise in custom, large-scale black and gray tattooing, his versatility with this delicate fine-line tribute was incredible. If you are looking for an artist in Westchester who can handle everything from massive realism projects to precision memorial pieces, I cannot recommend him enough. He didn't just give me a tattoo; he helped me create a beautiful, permanent connection to my sister that I will cherish forever. Thank you, Caesar!
Now, You Know. Here's What To Do With It.
Every session at Killer Silver Tattoo Studio uses Killer Silver 7, the same safe tattoo ink that passed REACH testing at CTL in Bielefeld, Germany, in 2013.
