Brand new 20oz Stanley coffee tumbler. Please read carefully- They say south shore bank due to an error with Stanley and they wouldn’t take them back. As you can see I have plenty of these and the handle tumblers. My husband and best friend swear by these coffee tumblers and use them daily. ** I have multiple in stock ** They do not come in their own boxes as they came in lots of 4 for the tumblers and 6 for the coffee tumblers I uploaded a quick video showing the inner piece that when its locked in it will not fail. Never had an issue with it falling in as long as its locked in place. We also put them in the dishwasher every day. Havent had any issues and been using them for a year now. Please ask me any questions.
