Each box contains 2 refills and holds up to 600 newborn diapers. Simply cut the refill with the kid-safe cutter located inside the access door, discard, and tie a new knot in the remaining bag. Each Dekor Refill is one long continuous liner with no preset perforations or size, which means you can empty as often as you wantwhether its after one particularly stinky change, or when the pail is totally stuffedand use only what you need. Emptying the pail is super-easy. Dekor Mini Refills are made of 20% recycled materials (a mixture of post-consumer and commercial) and infused with a pleg baby-powder scent that helps neutralize odors.
