Unopened size 3 diapers. If you have ever wanted to try them, but needed more than their trial pack, this is the way to go. We love them and will continue to use them, but my daughter has started to leak through at night as she is ready for the next size up. Compared to leading brands, The Diaper offers up to: 12-hr leak protection to help prevent nighttime wakeups 70% more liquid capacity + 4x faster absorbency for fewer leaks 3x drier skin to minimize likelihood of diaper rash Ultra-soft, apparel-grade materials for comfort Wetness indicator alerts when a change is needed
