Details: These unique mugs are cut down from Erlenmeyer flasks. Perfect for coffee or tea. As a bonus, because they are wider at the base than the mouth, they resist tipping and spilling on your grade book. These borosilicate mugs also make eye-catching candy dishes or pencil holders. A great gift idea.
