40 Pieces (Same Size) Very Small Solid Rubber Stoppers - Size #000-13mm (0.51in) x 8mm (0.31in) - 17mm (0.66in) Long - Black Lab Plug

So, I used the stoppers for an unusual purpose... I kept having wasps crawl in the holes in my square tube railing and build nests. Annoying to have the wasp patrol come out each time I walked in our out of the house. I’d no sooner kill one nest than another would pop up. It was actually pretty funny watching the wasps go WTF? Where’s the holes? After I plugged the holes with these stoppers, no more wasps! Bought a second time after one stopper fell out after many years and I couldn’t find my the rest of my first order. Worked just as good as the first time.

Good little product fits where I need it.

These work perfectly for how I needed to use them, but I needed exactly 40 and the box of 40 contained 36. I'll have to buy another box to finish my project. I'm sure I'll find something to use the leftovers for some day.

Our 3 year old and kitten decided the original plug for our AC drain was a toy and as you can imagine, it became a wet mess. They still find them intriguing but having a box of 40 has helped us to still have some backups when one gets stolen by the little ones!

Used these to cover the sharp screws coming in from the roof.

Reasonable price - uniform size and decent quality.

I used them for my coolers with missing plugs... Awesome

It's pretty hard to mess up on a rubber stopper. They work as expected. I only gave 4 stars because a couple of them had pitting in the rubber, so I tossed those ones. I only needed 11, so I still have plenty to choose from. However, if someone needed all of them, having the odd dud mixed into the bunch could be irritating.
