Review on 🍱 Rubbermaid Easy Find Lid Square 1-1/4-Cup Food Storage Container, 12 Pack, Red/Clear by Rebecca Carter

A bit expensive but very useful and durable. One caveat - "microwave safety" is actually limited by the boiling point of water. In particular, DO NOT heat greasy or oily food in containers to "FULL" temperatures as this will scratch the containers and possibly peel the plastic of your food. Oils and fats can easily reach temperatures of 400-600 degrees Fahrenheit or higher when cooking high above water at 212 degrees Fahrenheit (or lower at altitude). Therefore, switch containers with greasy or oily foods to ceramic or glass bowls away from high heat. Frozen foods usually fall out and separate from their beautiful rubber-lined containers before the fat gets too hot.
