Using these canisters is a breeze. You can use them to store all sorts of things like snacks, office supplies, or small toys. To make them extra special, just pop on your favorite minis. When it's time to clean, you can simply put them in the dishwasher. They're also microwave - safe, so you can use them to heat up food in a pinch. Just make sure the lids are off when using in the microwave. For long - term use, avoid dropping them on hard surfaces as it might crack the melamine. Keep them in a dry place when not in use to maintain their quality.
