This is a set of Aprica's NIOI-POI bags. It's very easy to use! Just open the diaper with one hand and throw it away! You can dispose of diapers hygienically! The triple-layer film provides 99% odor prevention and antibacterial properties to shut out odors! My child was potty trained early, so I didn't use this at all, and I'm selling it. I took it out of the box once, but it's new and unused. Please refrain from purchasing if you are concerned about home storage. There are no pets or smokers in the house.
