Frequently Asked Questions

Is Radiko stainless steel safe for daily use?

Yes. Our products are made from medical-grade 316 stainless steel — the same material used in surgical instruments and food processing equipment. They're independently SGS-tested and confirmed free from harmful levels of lead, cadmium, and nickel. Safe for adults, kids, and everyday meals.

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, non-toxic, and safe for everyday food contact. It's the same grade used in most professional kitchens and trusted brands.

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 surgical instruments and food processing equipment.

At Radiko, we offer products in both grades so you can choose what fits your needs and budget — and rest assured that every piece, regardless of grade, is independently SGS-tested and confirmed safe from harmful heavy metals.

Are Radiko products dishwasher safe?

Yes, completely. Stainless steel is non-porous and won't degrade in the dishwasher. For best results and to maintain the polished finish, we recommend air-drying or towel-drying after the cycle.

Will Radiko chopsticks or cutlery rust?

No. Medical-grade 316 stainless steel is highly corrosion-resistant — far more so than standard cutlery. With normal care, your Radiko products will stay rust-free for decades.

Are your products BPA-free and free of plastic coatings?

Yes. There are no plastics, paints, or coatings of any kind. What you see is solid stainless steel — nothing to chip, peel, or leach into your food.

Are Radiko products safe for children?

Absolutely. Because there are no coatings, no BPA, and no harmful heavy metals, our products are safe for kids learning to use chopsticks or cutlery. Many of our customers buy Radiko specifically for their families.

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

Most budget stainless cutlery is made from lower-grade 201 or 304 steel, often with unknown sourcing and no third-party safety testing. Radiko products use medical-grade 316 stainless, are manufactured in Taiwan under strict quality controls, and are independently SGS-certified. You're paying for verified safety, durability, and craftsmanship — not marketing claims.

How do I care for my stainless steel products?

For our stainless steel chopsticks and cutlery, 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 designed to last a lifetime.

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?
