OriginalLUX is perfect if you order a LARGE at the counter, or if you change your coffee size as much as your knickers. She's got the 6, 8 & 12oz fill lines etched on the side so your indecisiveness is legit. Don't worry #wevegotyou. Her base & lid is interchangeable with both the MiniLUX & LittleLUX. She's definitely the most popular kid at school.
