About the materials used in THE LIMELY

What is surgical stainless steel?

The main material used at THE LIMELY is surgical stainless steel (SUS316L) . It is the highest quality 316L stainless steel , which is also used in medical equipment, and is characterized by its rust-resistant properties.

It has almost the same corrosion resistance as common precious metals (18K gold and platinum 900) and is known as a material that does not cause metal allergies . In addition, the color of the metal is brighter than that of pure titanium, making it attractive for its high designability as an accessory.

It is said that the main cause of metal allergies is when metals corrode due to sweat or body fluids, releasing metal ions that bind to proteins in the body and become allergens. 316L stainless steel is resistant to corrosion and heat, so it has the advantage of not deteriorating easily even when worn for a long time .

What is nickel-free?

Nickel-free is a measure to reduce the burden on the skin by using materials and coatings that do not contain nickel (or contain as little nickel as possible).

Nickel is generally used to create a shine similar to that of gold or platinum, but THE LIMELY uses a nickel-free coating to achieve both a high level of luster and corrosion resistance while reducing the burden on the skin.

By applying a nickel-free coating to surgical stainless steel, we are able to achieve both a beautiful finish that is comparable to gold or platinum , as well as anti-allergy properties .

What is PVD coating?

PVD coating is an abbreviation for Physical Vapor Deposition, and is an advanced process that enhances the durability of metal surfaces . By protecting the surface with titanium nitride or aluminum nitride, a coating with excellent wear resistance, adhesion resistance, and corrosion resistance is formed.

It is said to be a skin-friendly metal processing method, and is characterized by containing as few metal allergens as possible. By applying PVD coating to 316L stainless steel, which is naturally hypoallergenic, we aim to provide better anti-allergy measures and reduce the burden on the skin .

Prevention of metal allergies

Metal allergies are thought to develop through three processes:

1. Metal coming into contact with sweat or body fluids
2. Metal is corroded and dissolves into metal ions .
3. The body overreacts to the dissolved ions and becomes an allergen

In other words, by taking measures at some stage , it may be possible to prevent the symptoms of metal allergies. At THE LIMELY, we value designs that use rust-resistant materials and coatings to prevent corrosion even when exposed to sweat or moisture, and to prevent ionization .

As a skin-friendly accessory

THE LIMELY accessories are designed to be gentle on the skin even when worn 24 hours a day . However, constant friction on the skin can cause problems. It is important to take them off periodically to give your skin a rest, and to take care of your skin .

We hope that our accessories, which combine stylish designs that allow you to look stylish anywhere and quality that will withstand long-term use , will help you to enhance your style more comfortably.

*The causes of allergies vary from person to person. We cannot guarantee that no reaction will occur in all people. If you notice any abnormalities on your skin, discontinue use immediately and consult a specialist.
