The Ultimate Lunch Box Bundle

Both our Hot n Cold hero box and Five compartment lunch box are completely dishwasher safe.
Place all components in the dishwasher.

The silicone seal on the hot/cold bento box lid is not removable, please remove the silicone seal on your five compartment lunch box and place separately in dishwasher.

For the insulated food jar, remove the lid and carefully peel off the silicone seal. Wash all parts in
the dishwasher. Reattach the silicone seal by pressing it down and rolling it over the jar’s inner
rim.

**Tip:** Use fragrance-free dishwashing liquids or tablets to avoid leaving a taste on the silicone.

Our insulated food jar uses advanced vacuum wall technology to keep your food at the right
temperature. Here are some tips for the best performance:

For Hot Foods:

1. Preheat the jar by filling it with boiling water for 10 minutes, then empty it.
2. Heat your food until piping hot (hotter than if you were serving it immediately).
3. Quickly transfer the hot food into the preheated jar and secure the lid.

For Cold Foods:
Pre-chill the jar by placing it in the freezer for 10 minutes or filling it with ice water for 10 minutes, then empty it.

Transfer your cold food into the pre-chilled jar and secure the lid.

Important Tips:

The jar works best with wet foods like soups, noodles in sauce, or saucy dishes. Fill it almost to the top to minimise air, which cools the food faster.

Avoid using the jar for solid foods like chicken nuggets or sandwiches as they cool very quickly and become soggy.

Don’t put the lunchbox in the fridge or next to an ice brick when using it for hot foods.

Performance:

Hot:

Keeps food warm for up to 4 hours (up to 5 hours in the lunchbox). Please note this is dependent on following the guidelines above.

Cold:

Keeps food cold for 6 hours (up to 7 hours in the lunchbox).

Consider if this is sufficient to meet the needs of your child. You can read more here about how to get the most out of your insulated food jar: https://www.nudierudielunchbox.com.au/blogs/recipes/warm-lunches-made-easy-how-to-get-the-most-out-of-your-insulated-food-jar

Yes, silicon can stain when exposed to highly coloured foods like pumpkin soup, watermelon or tomato. These stains usually fade over time.

Yes, the largest section of our hot n cold hero box is 17.5cm x 10.5cm and fits a sandwich cut in half and stacked (snack pot removed). The square section is 10.5cm x 10.5cm and will fit a smaller range of bread or larger sizes with the crusts cut off.

The largest section of our five compartment lunchbox is 12cm x 11cm. It will fit a sandwich made with traditional sized loaves of bread (eg the type you might buy from the in-house bakery section at Coles or Woolworths). It does not fit larger sized loaves of bread like Helga's or Wonder White without cutting off the crusts.

Store your products dry, with the lids off/open, and any silicone seals removed to prevent any food smells from building up.

Our lunch boxes are tough and durable, but scratches and dents may occur over time. Silicone may also stain as mentioned above.

Our updated Hero lunchbox now features two flip-open plastic coloured clasps attached to the lid. These clasps close downwards and provide a simple, easy-to-open mechanism, making the lunchbox suitable for young children aged 3 years and up. We recommend practicing opening and closing the clasps and the insulated food jar with your child before first use to ensure they can manage it confidently.

**Tip:**

The insulated food jar has an easy locking mechanism but if the handle is pumped up and down multiple times it may create a vacuum. If the lid becomes vacuum-sealed, place the jar in cold water for a few minutes to break the seal.

Our five compartment lunch box is suitable from around 4years of age. The clasp is tight but generally manageable for young children once show how to open and close it.

Use vinyl stickers directly on the outer surface of the lunchbox or food jar.

Silicone can absorb odors from scented dishwashing liquids or tablets. To prevent this, we recommend using fragrance-free dishwashing liquids or tablets, often labeled as "eco products" and available at most supermarkets. If your silicone products develop a soapy smell or taste, try one of the following deep cleaning methods:

How to remove smells from silicone:

1. Vinegar + Baking Soda Soak

• Mix equal parts hot water and vinegar in a sink or bowl.
• Add 1 teaspoon of baking soda (it should fizz).
• Let the silicone soak for a few hours or overnight.
• Rinse and dry. Repeat if needed.
  

2. Boil in Water + Vinegar

• Fill a pot with 3/4 water and 1/4 vinegar (enough to cover the silicone).
• Boil for 10-15 minutes, then rinse and dry.

Our lunchboxes are crafted from high-grade 304 food-safe stainless steel and have been independently tested to meet FDA food safety standards. We use 100% pure silicone, also independently tested and LFGB certified—the highest standard for food-safe silicone products.
