Square Rubber Drain Cover

This is a nice reasonably weighty drain cover. I like the optional suction cups - I've tried it both ways and don't really feel the suction cups are needed but they're there if you want them.

There's nothing like a terry towel for scleral lens safety, because a towel will both prevent lenses going down the drain and make sure they don't crack if they land a porcelain sink. However, if the only real worry is making sure they don't go down the drain, a rubber drain cover is very helpful.

Truth: the manufacturer's description was not very relevant, was kind of over the top ridiculous, and was kind of sketchy as regards accuracy, so I'm not going to bother including it. If you have questions not answered here, please let us know.
