Size 1 diapers fit infants between 7-17 pounds. Esembly diapers are made with organic cotton and, when paired with Esembly outer covers, are very absorbent and leak proof. We never experienced a single blowout! All snaps and elastic leg bands in perfect condition. Some stains as shown in photos, which is why I'm selling this as a set of 4 at a discounted price. Used to diaper one infant for approximately 4 months. Washed per Esembly's instructions. Recently strip washed in preparation for sell. Only selling because baby leveled up to size 2.
