Counterfeits often use materials without the stiffness of wire, like
When you pull wire from a spool, it can retain a strong curl.

Thorough quality control

計測器による厳密な検査

Strict inspection by measuring instruments

Introduced dedicated tensile testing machines and outer diameter measuring machines.
Using our company's standard test methods for wire strength, diameter, and so on,
We are measuring precisely.

専任検査員による試験

How to Purchase
For Individual Customers
Here is a list of online shopping sites that carry our products.
For corporate clients
We would like to introduce our sales distributors.
About Quality
What is it made of?
The wire is made of stainless steel, and the coating material is polyamide resin (nylon).
What is the difference between “7strands (1×7)” and “49strands (7×7)”?
"7strands (1×7)," which consists of seven strands of wire twisted together, is the most standard product used in jewelry making. "49strands (7×7)" is made by twisting seven sets of 1×7 wire together. It offers high flexibility, so we recommend it for creating complex designs.
Where is the manufacturing location?
All of our products are manufactured at our own factory in Osaka Prefecture.
Are the materials made in Japan?
We primarily use Japanese-made materials, but we also use some foreign-made materials.
About trouble
It's stainless steel, so why did it rust?
Stainless steel is not a metal that never rusts, but rather one that is "resistant to rust." Depending on storage conditions and the environment in which it is used, it may rust.
About Colors
Can you create a custom color for me?
We accept orders for custom colors. If you provide us with your desired color code or color sample, we will consult with the coating manufacturer to determine whether production is possible. If production is possible, you will be required to pay the cost of the nylon resin for the coating separately.
About Length (Custom Orders)
What are the different lengths available?
The basics are 10m rolls, 30m rolls, 100m rolls, and 1,000m rolls.
We can also accommodate other lengths upon request.
Other
What are the effects of stainless steel and nylon on the human body?

Since stainless steel is commonly used in tableware, household items, and even medical devices, it is considered a highly safe metal; under normal conditions of use, it poses no risk to human health.
*Please refrain from using this product, as we cannot be held responsible for any effects on the human body under conditions other than normal usage.

Since nylon (polyamide) is used in many everyday items and sports equipment, it is considered a highly safe material, and it poses no risk to human health under normal conditions of use.
*Please refrain from using this product, as we cannot be held responsible for any effects on the human body under conditions other than normal usage.

How should I store it?
Nylon-coated wires may fade due to UV rays, so please avoid storing them in direct sunlight or areas with strong UV exposure. Also, stainless steel wires may rust in humid areas or coastal regions, so please be cautious during storage.
I want to remove a nylon coating. Please tell me how to remove it.

SakuLux®The nylon coating is highly adhesive, making it difficult to strip the wire without damaging it. While it is possible to strip it, we cannot accept any responsibility for it.

Can I return or exchange it?

Please contact the store where you made the purchase.
