The Dental Timers pack contains 72 timers, each designed like a 3 1/2 inch tall plastic hourglass. These timers serve as an effective tool to ensure that kids brush their teeth for a sufficient duration to achieve a thorough cleaning.

The timers are set to last between 2 to 3 minutes, which is the recommended time for brushing teeth. The variability in time is likely due to the nature of the hourglass design. Once the timer is flipped, it will take approximately 2 to 3 minutes for the sand or liquid inside to pass through the narrow opening, signifying the completion of the brushing time.

The pack comes with an assortment of colors and styles, making it more appealing to kids as they can choose their preferred timers. However, its worth noting that the specific colors and styles may vary from pack to pack, ensuring a mix of options for users. The variation adds an element of surprise and novelty, making brushing teeth a more engaging and enjoyable activity for children.
