All of the stainless steel used in our products is high quality, food safe, corrosion resistant and independently tested. Most of our products like lunchbox and bento box are made in China responsibly from 304 premium grade stainless steel.
Our Double tier lunchbox is not leakproof but our bento box called The Grub Box is leakproof. Also the smallest size of leakproof container fits neatly inside the double tier lunchbox for carrying sauces or dressings.
The plastic caps we use are BPA/BPS free, non-leaching, toxin free polypropylene. It is a tough plastic, easy to clean but it is more brittle than normal plastic. We do have an all steel cap option. All caps have a food grade silicone sealing ring. Silicone is toxin free. Our leakproof lunchbox and bento box use the food grade silicone rings too.
Stainless steel can be washed in dishwasher but be mindful that water marks may appear on your steel products. To get rid of water marks mix a cup of vinegar in warm water or 4 tablespoons of baking soda in warm water and wipe it down with it using a dish cloth on your lunchbox or bento box
304 or 18/8 grade stainless steel does not retain flavours or smells. If you have already given it a good scrub with a bottle brush and warm soapy water try mixing a quarter or a cup of vinegar and 4 tablespoons of baking soda in warm water and let it soak overnight. Rinse your lunchbox or bento box well with warm soapy water and then with plenty of fresh water and leave upside down to drain.
With hot soapy water and detergent - or in the dishwasher! Do not use bleach, harsh chemicals, abrasive cleansers or pads. With proper care and cleaning, your stainless-steel lunchboxes or bento box may be used for years and years to come.
The 600ml cups are sanded and deeply polished in the production so the surface is easily corroded by improper use. We recommend hand washing them in warm soapy water to retain their polish. All our lunchbox and bento box are dishwasher safe.
