LunchBots are made from durable 18/8 stainless steel and designed to last a lifetime! ALL LunchBots products are dishwasher safe for a simple and easy clean up

Stainless steel, like all metals, cannot be microwaved. Metals reflect microwaves back and forth and can generate enough heat to potentially ignite something in the oven. To be safe, please do not put your LunchBots in the microwave.⁠
