Frequently Asked Questions

Is Radiko stainless steel safe for daily use?

Yes. Our chopsticks are made from 316 marine-grade stainless steel with a Japanese SPS resin handle, and they're independently lab-tested by SGS and Intertek, with no lead or cadmium detected. Our flatware rests are made from food-grade 304 stainless steel.

Are disposable chopsticks unsafe?

Most disposable chopsticks tested in published studies (Taiwan and Singapore) were within local limits. Some wooden and bamboo chopsticks are treated with sulfur dioxide during production. We simply offer a reusable alternative: a pair with clearly disclosed materials, care instructions, and lab test results you can review.

What's the difference between 304 and 316 stainless steel?

Both are excellent food-grade stainless steels, and both are widely used in high-quality kitchenware around the world.

304 stainless steel is the industry standard for cutlery and cookware — durable, corrosion-resistant, and suitable for everyday food contact. It's widely used in professional kitchens.

316 stainless steel is a premium upgrade. It contains molybdenum, which gives it even greater resistance to corrosion, salt, and acidic foods (like citrus, tomato, and vinegar). It's the same grade used in marine, pharmaceutical, and food processing equipment.

At Radiko, our chopsticks are made from 316 stainless steel and our flatware rests from food-grade 304 stainless steel. Our chopsticks are independently lab-tested by SGS and Intertek.

Why 316 stainless steel instead of 304?

Both are common in food-contact use. 316 contains molybdenum, which gives it greater corrosion resistance than 304, a thoughtful choice for chopsticks that are washed and reused every day. Our flatware rests use food-grade 304 stainless steel.

How do I use the utensil rest? Is there a designated spot for chopsticks?

Our rest features a multi-use design with specialized resting grooves and a center divider to hold different utensil combinations cleanly:

• Asian Dining: Rest your chopsticks comfortably on one side while holding a soup spoon on the other.

• Western Dining: Hold up to three pieces of flatware (fork, knife, and spoon) side-by-side simultaneously.

Are Radiko products dishwasher safe?

Yes, our stainless steel chopsticks and flatware rests are dishwasher safe. For best results and to keep the polished finish, air-dry or towel-dry after the cycle. Our 24K gold-plated chopsticks are hand wash only.

Will Radiko chopsticks or cutlery rust?

They're built to resist it. 316 marine-grade stainless steel is highly corrosion-resistant, more so than standard 304 cutlery. With normal care and thorough drying, your Radiko products are made to stay rust-resistant for years.

What are Radiko chopsticks made of?

The tips are 316 marine-grade stainless steel, and the handles are Japanese SPS resin, a heat-resistant material. SGS tested the handle and detected no lead, cadmium, or phthalates, with no change after heat testing to 482°F (250°C). Our flatware rests are solid 304 stainless steel with no coatings.

How is Radiko different from other stainless steel sold on Amazon?

Many budget options don't list their steel grade or share test results. Radiko chopsticks are made in Taiwan from 316 marine-grade stainless steel and are independently lab-tested by SGS and Intertek. You're paying for materials you can verify, lasting durability, and careful craftsmanship.

Where can I see your test reports?

You can find test details for our chopsticks on our Certifications & Safety Standards page. If you have questions about the results, feel free to Contact us.

How do I care for my stainless steel products?

For our stainless steel chopsticks and flatware rests, simply wash with soap and water, or place in the dishwasher. Avoid abrasive steel wool, which can scratch the polished finish. With basic care, they're made to last for years.

How do I care for my 24K gold-plated chopsticks?

For our 24K gold-plated chopsticks, please hand wash only with mild soap and warm water, then dry gently with a soft cloth. Avoid the dishwasher, abrasive sponges, and harsh detergents — these can wear down the gold plating over time. With proper care, your gold-plated chopsticks will retain their beautiful finish for years.

Can I put my gold-plated chopsticks in the dishwasher?

No — hand wash only

How does a Radiko flatware rest protect desks and study tables during meals?

The elevated design of our 304 stainless steel flatware rest keeps the food-contact tips of chopsticks, forks, and spoons lifted off your workspace surface. This helps prevent sauce drips, oil marks, and stains on laptop areas, desk pads, and paper notes during work-from-home or student meals.
