About This Product
The SEIDO Stainless Steel Lunch Box set offers brilliant value at £35.99 for three 800ml containers—perfect for meal preppers who want durability without the plastic guilt. These are genuinely tough: stainless steel construction with glass lids featuring their Quad Lock steam vent system keeps food fresh and prevents leaks. They're microwave, oven, and dishwasher safe, making reheating and cleaning effortless. The 4.4-star rating from 63 reviews shows real customers love them, and they're stainproof and 100% chemical-free, so no nasty odours lingering after curry night. At the mid-to-upper end of the £18.99-£41.99 price range, you're paying for quality that'll last years, not months.
These containers genuinely transform meal prep from a chore into something sustainable. The glass lids let you see what's inside without opening them, and the steam vent design means you won't get exploding food in the microwave. Whether you're batch-cooking Sunday lunches or storing leftovers, the three-pack covers most weekly needs. If you've been eyeing meal prep containers but worried about plastic degrading or staining, this SEIDO set solves that completely.
Frequently Asked Questions
Common questions about SEIDO Stainless Steel Lunch Box Microwave Safe Food Meal Prep Containers (3 x 800ml) Leakproof, Stainproof, Oven & Dishwasher Safe 100% Chemical Free with Quad Lock Steam Vent Glass Lid, answered with the latest pricing and product data.
Is the SEIDO lunch box set worth £35.99?
Absolutely. You're getting three premium stainless steel containers with glass lids for that price—comparable single containers often cost £15-20 each. The 4.4-star rating from 63 real reviews confirms they're built to last years, making them genuinely cost-effective for regular meal preppers.
What's the best use case for these SEIDO containers?
They're ideal for weekly meal prep if you cook in batches on weekends. The 800ml size works perfectly for lunch portions or storing sauces and sides, and the microwave-safe design means quick reheating at work or school without transferring to plates. The glass lids also make them great for fridge storage where you want to see contents at a glance.
How do these compare to plastic meal prep containers?
SEIDO's stainless steel and glass construction won't stain, absorb odours, or degrade like plastic does. They're dishwasher and oven-safe for more versatility, and they'll last significantly longer—most reviewers mention years of use without damage. The trade-off is they're heavier and slightly pricier upfront, but you'll replace plastic containers multiple times before needing new SEIDO ones.
Will the Quad Lock steam vent actually prevent leaks?
Yes, reviewers consistently praise the leak-proof performance for both liquid and semi-liquid foods. The steam vent design is the key—it allows controlled pressure release during microwaving while the seal keeps contents contained when closed and stored upright in your bag or fridge.
