The bin is a well-known brand and very hygienic to use. Its idea is to prevent diaper odors from leaking by twisting each diaper individually inside an antibacterial bag. It holds up to 33 diapers and is very easy to use. Special refill bags are available at Mothercare, Mumzworld, and Amazon, and you can use regular bags if you want to save money. It has many reviews on YouTube where mothers highly praise it. I'm selling it for 50 SAR as I no longer need it.
