Quick answer

Yes, the Peanuts Gentle Reminders 4-Pack 18oz Stoneware Travel Cup with Lid is both microwave and dishwasher safe, making reheating and cleanup easy.

Why stoneware matters for microwave use

Stoneware is a durable ceramic material that handles heat well, which is why this travel cup set is safe for the microwave. However, always check that the mug isn't cold before microwaving to avoid thermal shock.

What about the lid?

The BPA-free plastic lid with sliding lock is not microwave safe—only the stoneware cup itself can go in the microwave. Remove the lid before reheating.
