SIZES
The sizes given indicate the total length of the bracelet including the clasp. Alternatively, a size table to determine the size based on your wrist circumference is provided in the respective product description under “DETAILS”.
This is how you measure your wrist circumference: Measure at the desired point so that the measuring tape fits skin-tight (do not pull hard). Now you can read the correct size using the size chart. If you are between two sizes, choose the next size up.
If you don't have a tape measure, you can place a piece of string/thread or a strip of paper around your wrist and mark the point where the two ends overlap. Last but not least, place it on a ruler or ruler so you can read the measurement.
We want to make sure you find exactly what you're looking for. Take a look at our illustration and find your desired chain length.
If you don't have a tape measure to hand, you can place a piece of string/thread or a strip of paper around your finger and mark the point where the two ends overlap. Last but not least, place it on a ruler or ruler so you can read the measurement. You can then choose the right size using the table below.

MATERIAL & CARE
Our aim is to provide you with long-lasting jewelry of the highest quality
To offer quality that can accompany you everywhere so that you don't have to worry about damaging it. For this reason, most of our products are made of 316L stainless steel and specially coated with DLC "Diamond-like Carbon". But to complement our unique design, many of our products are refined with carbon or forged carbon or, like our trailers, made from 100% carbon.
Most people know carbon from the automotive industry, but don't know what lies behind this unmistakable look. Actually, the material “carbon” doesn’t even exist. The material we use and which can also be found on cars, bicycles or airplanes is a composite material or a mix of materials. Carbon refers to carbon fibers that lie in a plastic matrix. This so-called matrix consists of an epoxy resin, which is a mixture of different
chemical substances. This is what gives the carbon fibers their stability. This material mix creates a material that is highly resilient but also very light at the same time
is. When the carbon is fully hardened, we will make it into your pieces of jewelry on site. We have aligned our brand and anchored it in our name out of our dedication to this complex material.
Forged Carbon is a little less known. The pattern of
“Normal carbon” is uniform and not individual. Whereas Forged Carbon is a little more exciting and the surface is somewhat reminiscent of marble. Lamborghini started it all. They were one of the first to use the material on a large scale in their cars, which made it famous. The production is similar to conventional carbon, except that with Forged Carbon, fiber snippets and not whole strands are placed in epoxy resin. It is also produced like carbon and can be further processed by us.
That's no problem, you can have any product engraved at your local jeweler or similar. Our carbon pendants and rings can also be easily engraved. Unfortunately we can no longer offer this service.
There are several advantages of stainless steel jewelry compared to silver or gold jewelry:
Durability: Stainless steel is a very robust material and resists scratches, wear and tear and rusting. In comparison, gold and silver jewelry can be easily scratched and tarnished, shortening its lifespan.
Price: Stainless steel is typically cheaper, making it an affordable alternative.
Ease of Care: Stainless steel is easy to maintain and requires no special cleaning products or procedures. Silver and gold jewelry, on the other hand, often requires special cleaning to preserve its shine and beauty.
Allergy-Friendly: Stainless steel is hypoallergenic, making it good for people with sensitive skin or allergies to other metals such as silver.
Versatility: Stainless steel can be made in a variety of colors and finishes, making it a versatile option for jewelry designers. Fine jewelry typically has a more limited selection of designs and styles.
Loss: Some people know it: If you lose a piece of jewelry or even have it stolen, the loss is more manageable.
