Review on 🚽 Toilet Plastic Washers Replacement - Universal Solution for Improved Plumbing by James Dominick

There is nothing wrong with the product itself other than the description. They are not standard size. I could mount it but then if you try to raise the toilet seat all the way it won't hold because it's resting on the bolt. It also prevents the little plastic cover from closing over it. The thick black plastic piece seems to make it more visible, but it also had a larger top than the other screws I originally had, luckily I only needed the bottom so I could use it with my existing screw.
