Featuring barrier technology, the 7 layers work together to lock in odors and messes unlike ordinary 1-layer trash bags. Exactly what every nursery needs for odor protection. The refill bags hold up to 270 newborn diapers so you can spend less time running to the trash and more time with baby. You will never have to guess or keep count to know when the diaper pail refill needs replacement as a black indicator line tells you when the refills are almost out. So, keep them coming baby! An added bonus – the refills are continuous, so when those big blowouts happen you can easily dispose the mess without wasting an entire bag. Made to fit with diaper genie pails, you will not ever have to rely on anything else to keep your baby's nursery smelling fresh and staying clean. Now that is something mom and baby will love.
