SEIDO Cookware skillets are made from 100% 304 (18/8) food-grade stainless steel. All SEIDO Cookware products are made without intentionally added PFAS and without synthetic coatings. Because the skillets are uncoated, the cooking surface is the steel itself — there is no synthetic layer to scratch, flake, or wear away over years of use.

No. SEIDO Cookware skillets are uncoated by design. The cooking surface is 304 (18/8) food-grade stainless steel with no synthetic coating applied — no coating to flake, wear thin, or fail after hard use. Uncoated stainless steel takes high stovetop heat, sears properly, and scrubs back to clean metal. Food release comes from technique — preheating and fat — which the Learn library explains step by step.

SEIDO Cookware is sold in the United States on Amazon. This site is the brand's education and product-information home: read the guides, compare the three skillet sizes, then follow the 'See price on Amazon' link on any product page. Both the skillet lineup and the stainless steel lunch box 3-pack are sold on Amazon.com.

Every SEIDO Cookware product is covered by a 5-Year Warranty. That includes the uncoated stainless steel skillets in all three sizes — 8-inch (20 cm), 9.5-inch (24 cm), and 11-inch (28 cm) — and the stainless steel lunch box 3-pack. Because the skillets carry no synthetic coating, there is no surface layer whose failure cuts the pan's working life short.

Nothing — they are two names for the same pan: flat-bottomed, with flared sides, made for stovetop cooking. "Skillet" is the everyday term in the US; "frying pan" is equally correct and common in product listings. SEIDO Cookware's three stainless steel skillets — 8-inch (20 cm), 9.5-inch (24 cm), and 11-inch (28 cm) — are the same pans whichever name you use.

The 8-inch (20 cm) skillet is the single-portion size: two or three eggs, an omelet, one chicken breast, or reheated leftovers. If you cook for one but regularly make two portions, or want a single pan that handles everything, choose the 9.5-inch (24 cm) instead — it is the do-everything size in the range.

Choose the 11-inch (28 cm) stainless steel skillet. Its wider cooking surface browns a pound of ground beef, four chicken thighs, or a full skillet dinner in a single layer — and a single layer is what separates browning from steaming. For households of three or more, the 11-inch becomes the everyday pan, often alongside an 8-inch for eggs and sides.

It asks slightly more of you at first. The skill is preheating: heat the dry pan over medium, test with a drop of water — it should bead and glide — then add oil, then food. Once that habit is set, food releases cleanly. And because there is no coating, there is no release layer to wear out as the pan ages.

No. All three skillets are uncoated. The cooking surface is 100% 304 (18/8) food-grade stainless steel, without synthetic coatings and made without intentionally added PFAS. Release comes from technique — proper preheating and enough fat — rather than from a coating that wears down. That is a deliberate design choice, not a missing feature.

SEIDO Cookware skillets are sold in the US on Amazon.com. Each size — 8-inch (20 cm), 9.5-inch (24 cm), and 11-inch (28 cm) — has its own Amazon listing. Use the "See price on Amazon" link on each product page here to go straight to the listing. Every pan is covered by a 5-Year Warranty.

Yes. SEIDO Cookware stainless steel lunch boxes are microwave-safe by design. As a rule, metal containers should not go in a microwave, but these are engineered specifically for it — microwave reheating is a built-in product feature, not an exception to a rule. Reheat lunch directly in the container at the office, with no transfer to a separate dish required.

SEIDO Cookware stainless steel lunch boxes come as a 3-pack, 27 oz (800 ml) each. That capacity fits a full adult meal — a protein, a grain, and vegetables — which makes the set practical for office lunches, gym meals, and weekly meal prep. All three containers are the same size, so portions stay consistent across the week.

Three containers cover a realistic meal-prep rhythm. Batch-cook on Sunday, portion three meals, and lunch is handled for most of the work week — one container in your bag, one in the fridge, one being cleaned. A single container forces daily cooking and washing; three let you cook once and eat several times.

For repeated daily use, stainless steel is built to endure. It resists stains from tomato-based sauces, resists curry and garlic odors, and resists warping and wear through repeated reheating and washing. SEIDO Cookware containers are also made without intentionally added PFAS and without synthetic coatings. The case for stainless steel is durability: it is built for repeated daily use.

SEIDO Cookware lunch boxes are sold in the US on Amazon.com. The set includes three stainless steel containers with lids, 27 oz (800 ml) each, and every set is backed by a 5-Year Warranty from SEIDO Cookware. When you are ready, see price on Amazon.

Yes. Stainless steel does not stain, does not hold onto food odors, and survives daily dishwasher cycles without clouding or scratching the way plastic does. SEIDO's Prep Series containers are 100% 304 (18/8) food-grade stainless steel, sized at 27 oz (800 ml) for full meal portions.

Most stainless steel containers are not microwave-safe — but SEIDO's Prep Series lunch boxes are engineered specifically for the microwave and SGS-tested for it. That removes the biggest compromise of steel meal prep: reheating in the same container you carried.

SEIDO Prep Series containers are dishwasher-safe, tested by SGS to EN 12875-1 across 50 wash cycles. Daily washing is exactly what they are built for — no hand-wash-only asterisk.

Yes — SEIDO Prep Series containers are refrigerator and freezer safe, SGS tested. Batch cook once, refrigerate the front half of the week and freeze the rest.

No. A non-porous 304 stainless steel surface does not absorb pigments or aromas, so tomato-based sauces, curries and dressings rinse away completely — the next meal never tastes like the last one.
