I bought two pair of these on the last woot. One was misformed. There is a small hole on the bottom and if you place these in the dishwasher, the inner glass fills with water that is impossible to remove. These are not good products and do not keep coffee hot as other double walled cups do. They do look very good and the remaining 3 are displayed on my windowsill.
Are the latte mugs microwave-safe?
