Baby bottles. We use a bottle warmer that heats the bottle with steam, but yeah, I’d say breast milk/formula counts. That being said, I don’t think I’ve ever seen bottles not rated as being safe for bottle warmers? And you’d never put a bottle in a microwave (process is too harsh on breast milk and consequently ruins much of its nutritional value, not sure about formula).
