A 15-ounce sublimation mug with Luke's Diner logo is a coffee mug that has been created using the sublimation process. Sublimation is a printing technique in which the design is transferred onto the mug using heat and special inks, ensuring that the image is permanent and won't peel or fade over time. The fact that the mug is completely microwave and dishwasher safe means that it can be safely used in both the microwave to heat beverages and the dishwasher for easy cleaning. The microwave-safe feature allows you to reheat your drink without worrying about damaging the mug, while the dishwasher-safe feature makes cleaning up a breeze. As a fan of the fictional Luke's Diner from the TV show "Gilmore Girls," having the logo on the mug would add a touch of nostalgia and personalization to your daily coffee or tea routine. This type of mug is often a popular choice for gifts, collectors, or simply as a fun and functional item to have around the house or office.
