Hello, I thought toilet wedges too, but brass or bronze up against a toilet bowl?? With ridges?? All I see is an accident waiting to happen!!! I know things were made better back in the day, and I am not a big fan of things being replaced by plastic. For shimming a wobbly toilet I have always used a wood shim, easy to adjust, won't damage the fixture, and easy to trim out of sight Regards, Lou
