I am so amazed at the quality of these joyjolt aroma double wall coffee glasses. This is the first time I have had glass coffee cups and I will probably never go back to ceramic. My only concern is that they feel very thin and light. The look of them is so chic. I love that they're double walled so that your coffee stays warm. I have used them with both cold brew and got coffee. These would be a perfect gift for any coffee lover.
