The SEIDO Cookware Range — Frying Pans, Lunch Boxes and Kitchen Tools
SEIDO Cookware makes seven products, sold in the UK on Amazon.co.uk: uncoated frying pans in 20, 24 and 28 cm, a stainless steel lunch box 3-pack, 800 ml (27 oz) each, a chef's knife, a honing steel and a serrated peeler. Each carries a 5-Year Limited Warranty; lunch box lid parts are covered for 1 year.
The range is deliberately small and built for everyday cooking. The frying pans — the Sear Series — have a bare 304 (18/8) stainless steel cooking surface; the lunch boxes — the Prep Series — go from fridge to microwave with the lid off; the tools handle the prep in between.

The range
Verified, not claimed.
A 304 (18/8) stainless steel cooking surface on every frying pan, 304 (18/8) food-grade stainless steel lunch box containers, made without intentionally added PFAS. The third-party test documents are published for you to read.
What is in the SEIDO Cookware range?
Seven products in three categories. Each is listed below with what it is made of and what it is for; every product page has the full detail and a Buy now on Amazon button.
- Frying pans (Sear Series): 20 cm (8 in), 24 cm (9.5 in) and 28 cm (11 in). A tri-ply clad body — a 304 (18/8) stainless steel cooking surface, an aluminium core and a 430 stainless steel exterior. Uncoated, made without intentionally added PFAS and oven-safe; each comes with a matching stainless steel lid.
- Lunch boxes (Prep Series): a 3-pack of 800 ml (27 oz) containers in 304 (18/8) stainless steel, each with a lid. Microwave-safe by design with the lid off; the container is lab-tested.
- Chef's knife: a VG10 steel core clad in Damascus stainless steel, a blade of about 22 cm (8.7 in) and an octagonal olive wood handle, in a hinged gift box. Hand wash only.
- Honing steel: a 20 cm (8 in) rod on a riveted handle, with a guard at the base of the rod.
- Serrated peeler: stainless steel, with a serrated blade for soft, slippery skins as well as everyday vegetables.
Which frying pan size do you need?
Match the pan to the portion. The 20 cm (8 in) is the egg and single-portion pan. The 24 cm (9.5 in) is the everyday size, and the one to choose if you are only choosing one. The 28 cm (11 in) is for family meals and batch cooking, where a wider surface keeps food in a single layer so it browns instead of steaming.
All three share the same construction and the same uncoated cooking surface; only the capacity changes. Measure your hob rings before you choose the largest size.
Why are SEIDO Cookware frying pans uncoated?
Because a coating is the part of a pan that wears out. The cooking surface of every SEIDO Cookware frying pan is bare 304 (18/8) stainless steel, made without intentionally added PFAS and without synthetic coatings, so there is nothing to scratch, flake or wear thin.
Bare steel also browns directly. It builds fond — the browned layer that becomes the base of a pan sauce — and takes the steady heat that searing needs. It asks for one habit: preheat the dry pan over a medium heat for a couple of minutes, test with a drop of water, then add oil and food.
How does the lunch box 3-pack fit a meal-prep week?
Three identical 800 ml (27 oz) containers match a simple rhythm: cook once, portion three meals — two for the fridge and one for the freezer — and lunch is ready for three days. Each container holds a full adult lunch.
The containers are microwave-safe by design with the lid off — the container is lab-tested — so a packed lunch goes from the fridge to the microwave with no second dish. Reheat with food in the container, never empty or overfilled, in a microwave of up to 1000 W. The set carries a 5-Year Limited Warranty, with the lid parts covered for 1 year.
