This is a 4 pack of timers, (1, 3, 5, 10 minutes), they are different colors and the cutest little things! Would be great for kids, classrooms, the office, etc. I did not give 5 stars because when they arrived, almost all to the black top and bottom pieces were popped off. I easily attached them with a little hot glue and they are holding up well. They feel a heavier but more delicate with the glass than the usual small plastic timers that come with board games. Overall, these are nice little timers.
