Klean Kanteen 23oz Rise Food Box, Lunch

Product Description:
A real steel lunch box, no plastic anywhere. 23oz holds a sandwich and a side, or last night's lasagna. The silicone lid seals leakproof with snap-and-lock tabs, and a bendable corner lets you burp out trapped air for a tight close. Steel in the microwave sounds wrong, but the rounded edges are designed to prevent arcing, so you can reheat without dirtying a second dish. Oven safe too, up to 350F for reheating. 5.87 by 5.75 inches and under 2 inches deep, so it lies flat in a bag. Weighs 8 ounces empty.

Ingredients:
Base: certified 90% post-consumer recycled 18/8 stainless steel with Klean Coat powder coat finish. Lid: food-grade silicone. BPA, BPS, BPF, lead, and plastic free.

###

How to use:
Wash it before the first use. To seal, set the lid on, lift the flexible corner while pressing down to burp out the air, then snap the side tabs. Microwave the base only, never the lid, one box at a time, under 5 minutes, in a microwave 1000 watts or less, not touching the sides. Oven is base only too, up to 350F for 20 minutes, for reheating rather than cooking. Everything is dishwasher safe.

The Business:
Klean Kanteen is a family-owned company designed in Chico, California and responsibly made in China. Certified B Corp, member of 1% for the Planet, and Climate Label certified.

###

End Life:
Steel and silicone are both built to outlast the habit of buying containers. The base is endlessly recyclable through scrap metal. Silicone cannot go curbside, but lids are sold as replacement parts, so a torn seal does not end the box. Backed by a lifetime limited warranty.
