Review on Freshen Up Your Nursery with Munchkin Arm and Hammer Nursery Fresheners - Lavender or Citrus Scents, Pack of 5, Green by Kelsey Brown

I should have read the comments first. I was looking for a washer to screw onto the lid of our diaper pail. I ordered these and received these tiny ones that won't connect to my diaper pail. They have to change their appearance so as not to confuse us. It took forever but I found the link to the right item that most of us look for when we accidentally order them. Hope the link works for you. The item is called Munchkin Arm & Hammer Puck Baking Soda Cartridge Lavender Flavor https://www.amazon.
