Materials (earrings, ring, etc.)
At cuff-if, we pursue ``light and comfortable to wear,'' and are particular about details such as lightweight materials, metal fittings, and earring catches.
The metal fittings of earrings and piercings are all the same.

For those concerned about metal allergies from earrings
At cuff-if, we use medical grade stainless steel for all of our earrings, so we believe that there is no need to worry about metal allergies. However, if you would like to change the earring post or catch, such as titanium, 925 silver, or 18k gold, we will We would like to respond as much as possible. Please feel free to contact us.
Custom Ear Cuff/Custo Double Ring
cuff-if original interchangeable ear cuffs and dress-up double rings,
It is made from silver925. The silver color is the same color as silver925. The gold color is
Silver925 is coated with 24K gold (pure gold) thicker than usual.
Since silver999 (pure silver) is too soft to be processed into jewelry, jewelry made from silver925 is usually popular. Silver925 refers to the material made by adding about 7.5% of silver999. There are silver 925 products on the market that use nickel for this split, but nickel is the metal that is most likely to cause metal allergies, so we do not use nickel in our jewelry.
Silver products are a typical material that is unlikely to cause metal allergies. If you have experienced metal allergy symptoms from silver products, we strongly recommend choosing silver products that do not contain nickel.

About resin
cuff-if's original "imaginary stone". Generally, petroleum-derived resins are the mainstream, but cuff-if uses high-quality plant-derived resins that are less harmful to the human body, environmentally friendly, and reduce the environmental impact during production and disposal. We manufacture them one by one.
This resin is a high-quality material with high transparency like glass. The refractive index is also almost the same as glass.
About Jesmonite
Jesmonite ( JESMONITE® ) is mainly used in the production of homeware.
It is a water-based resin that does not contain any organic solvents or VOCs, and unlike the petroleum-based resins that have been widely used, it is known as a three-dimensional modeling material that is less harmful to the human body and environmentally friendly.
