About SEIDO Cookware
SEIDO Cookware is a cookware brand that makes uncoated, tri-ply clad stainless steel frying pans with a 304 (18/8) cooking surface, and stainless steel lunch boxes whose containers are 304 (18/8) food-grade stainless steel. Both are made without intentionally added PFAS and without synthetic coatings, carry a 5-Year Limited Warranty and are sold in the UK on Amazon.co.uk.
The name derives from 精度 (seido), the Japanese word for precision — a standard the brand is held to, not a statement of origin. This page covers the brand at a glance, what the name means, why the cookware is uncoated and what SEIDO Cookware makes.

What does SEIDO mean?
SEIDO derives from 精度 (seido), the Japanese word for precision. It is a fact about the name — and a standard the brand is measured against. Precision here means exact material grades, exact specifications and tolerances treated as promises rather than targets.
It is worth being direct about what the name does not mean: it says nothing about where SEIDO Cookware products come from. 精度 sets the benchmark for every specification on this site, from 304 (18/8) stainless steel to the 800 ml (27 oz) capacity of each lunch box.
Why uncoated stainless steel?
A coating turns a pan into a countdown. The surface doing the cooking is not the pan itself; it is a layer applied to the pan, and every applied layer wears. When it goes, the pan is done — regardless of how much good metal sits underneath.
SEIDO Cookware frying pans remove the countdown by removing the coating. The cooking surface is 304 (18/8) stainless steel — bare steel, not a coating. The frying pans and lunch boxes are made without intentionally added PFAS and without synthetic coatings — a simple statement: there is nothing on the pan that was not already the pan.
One honest surface asks a little more of the cook — a properly preheated pan, a little fat. Steel like this is built to be used hard and kept, which is why every SEIDO Cookware frying pan and lunch box is backed by a 5-Year Limited Warranty, not fine print.
What does SEIDO Cookware make?
Two product lines on this site. One standard. Every SEIDO Cookware frying pan cooks on a 304 (18/8) stainless steel surface over a tri-ply clad body, every lunch box container is 304 (18/8) food-grade stainless steel, and both lines are sold in the UK on Amazon.co.uk.
- Frying pans — three uncoated stainless steel frying pans: 20 cm (8 in) for eggs and single portions, 24 cm (9.5 in) as the everyday frying pan and 28 cm (11 in) for family cooking. Compare all three on the stainless steel frying pan hub.
- Lunch boxes — a stainless steel 3-pack, 800 ml (27 oz) each, with construction engineered to be microwave-safe. Built for meal prep, the office, the gym and the commute. Full details on the lunch box hub.
