Size Chart
RING SIZING
GOT A PRINTER?
Save the image above to your computer (right-click → Save Image As).
Print it at full size — make sure your printer's "fit to page" or scaling option is switched OFF.
Check the print is accurate: the grey bar at the bottom should measure exactly 3.5 inches. If it doesn't, reprint with scaling disabled.
Cut out the sizing tool at the top and wrap it around the finger you're buying for.
Whatever number lines up with the "READ SIZE HERE" marker is your size. Sitting between two sizes? Go up, not down.
NO PRINTER? NO PROBLEM.
Grab a strip of paper or a length of string and wrap it snug around your finger.
Mark the point where it overlaps, then lay it flat and measure to the mark with a ruler.
Match that measurement against the size chart below. If you land between two sizes, take the bigger one — a ring you can get off beats a ring you can't.

NECKLACE SIZING
BRACELET SIZING
Wrap a flexible tape measure around your wrist just below the wrist bone — the spot where a bracelet naturally sits. No tape measure? A strip of paper or string works: wrap it, mark where it overlaps, then measure to the mark with a ruler.
That number is your wrist size.
Now add room depending on how you want it to sit:
Snug fit: add 1/4 inch
Comfort fit: add 1/2 inch
Loose fit: add up to 1 inch
Working in cm? Same process — add 0.5cm for snug, up to 2.5cm for loose.
The brand for people who reject polish, softness, and mainstream approval.

Anita D.1/5Verified
The chein is totally thin and doesn't look as on the oics or on the video.
Georgi Z.1/5
I honestly thought the quality would be better. The lock is nice and heavy, but the chain has a little bit a cheap look and seems like it will break easily.. let’s see how it goes

He loved it ❤️
Jonathan S.5/5Verified
Paid $40 for this. Looked big and heavy in the picture. Shoulda read the comments. It’s small, not heavy at all and I don’t se the chain actually taking a beating like my jewelry does. SUPER disappointed.
Nathan D.1/5Verified
Great look. Too bad working key wasn't included
Michael H.5/5Verified
great design, but the material feels a little too light. I was expecting a more massive chain.
Joachim V.4/5Verified
Lighter than I expected! But super comfortable
Mr L.5/5Verified
Cool necklace
Alex P.5/5Verified
Not heavy at all, the chain actually feels like it’s made of cheap plastic. It’s so lightweight that it just can’t be made of metal.
