Using your Canvas Home Daniel Smith mugs is a breeze. Simply fill them with your favorite hot or cold beverage, like coffee, tea, or even a cold smoothie. These mugs are dishwasher - safe, but for the best long - term results, we recommend hand - washing them with a mild dish soap and a soft sponge. Avoid using abrasive cleaners or scouring pads as they can scratch the delicate glaze. When not in use, stack them carefully to save space, but make sure to place a soft cloth between each mug to prevent chipping. If you're planning to return the item, remember that it's covered under a 30 - day return policy. Just make sure to keep the original packaging and all parts intact.
