9 Pack (Same Size) Solid Rubber Stoppers - Size #6-33mm (1.29in) x 25mm (0.98in) - 28mm (1.10in) Long - Black Lab Plug

Works like it’s supposed to

These solid rubber stoppers and very solid indeed. It takes some effort to push them in and pull them out, but they are impervious to wear and tear.

Great fit for a 3 liter wine bottle. I like to use these just in case the wine is not finished.

I used 2 of these to pressure test a NA miata radiator and they worked very well.

They did the job they were designed to do. I had no issues. Not sure what else to say.

Used to finish a project

Yay whatever

These are the perfect size for plugging female garden hose ends for the winter to keep insects and dirt out.
