When microwaving acidic foods, stir frequently to avoid splashing the lid and limit microwave time to 2 minute intervals. Please note that very oily or acidic food (such as tomato soup) may cause staining and even burn marks on the lids. Can I also microwave the lid? Yes! We have specifically designed the lid to remove the need for single-use plastic cling film to prevent splatter when microwaving. Just ensure the lid lock is popped open (to prevent pressure build up and to release steam), and you’re good to go. Can I put it in the dishwasher, freezer and oven Yes! The meal prep sets are dishwasher-safe (lid is top rack only), freezer-safe, and the steel box is oven-safe (not the lid). When freezing, take care not to over fill, particularly if meal prepping liquids as they can expand when frozen. How do I open the lid? These are leak proof due to the vacuum seal in the lid, but they are hard to open (nearly impossible until you break the seal). Do this by pushing the button to release the lid lock. The lid opens more easily if you do it slowly rather than quickly. How do I look after my meal prep sets? All seals and the lid lock valve (the grey silicone part ONLY, do not remove the actual lid button) are fully removable for deep cleaning. We also advise washing all parts with warm soapy water before you use them for the first time. ## Features - STAINLESS STEEL LUNCH BOX – Elevate your mealtime with our sleek, high-quality microwavable stainless steel lunch box.

Stainless steel, can go in the over or microwave to reheat, no toxic chemicals or microplastics going into my body. The only downside is that they are a little expensive. They seal, and are leakproof as far as my experience goes. The lid is only secured with a gasket and an airtight lock, so I wouldn't shake them about upside down, but very very good.They're so good that I have a new found love and confidence in this brand that I never knew before, and am looking into more of their products. ### ⭐⭐⭐⭐⭐ Fab lunch box *by on Reviewed in the United Kingdom 19 August 2026* Great for lunch, the perfect size, love that you can lock it too so the lid isn’t coming off, I’m yet to put anything warm in or likely to leak so unable to comment on that yet. But easy to clean and good sleek looking design ### ⭐⭐⭐⭐ Nice container, but... *by on Reviewed in the United Kingdom 2 September 2025* It's a good size and lid seems to stay on when being transported. However, I used it in the microwave and wasnt aware it was to be in there max. 2 mins and I had it in for 3 mins. It was v hot to the touch and the lid had popped open at the corner. There was an odd taste to my food as well - some sort of slight chemical taste, which was a bit concerning but I suppose it may have been due to fact that I'd microwaved it too long! Will come back and report the next time I microwave and make it less than 2 mins to see if it has the same taste. ## Frequently Bought Together - BLACK + BLUM Microwavable Stainless Steel Lunch Box | Multi-Function, Vacuum Sealed Container for Healthy Food | Portable and Stackable Food Storage for Office and Outdoor | 30 oz / 900ml - Black+Blum Nesting Cutlery Set | 3 Piece Stainless Steel Compact Travel Cutlery Set (Knife, Fork, and Spoon) Portable Tableware with Snap Shut Case, Silver - Black+Blum Insulated Lunch Bag, 6.7L - Leak Proof Bag for Adults and Kids with Roll Top Construction - Made with Recycled PET and BPA Free - Food Bag for On The Go, Slate --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/520453285-lunch-box-microwave-safe-stainless-steel-900ml-leak-proof-airtight](https://www.desertcart.tn/products/520453285-lunch-box-microwave-safe-stainless-steel-900ml-leak-proof-airtight) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-31*
