Quick, Inexpensive, Perfect
I just needed one rubber stopper. I was expecting to go online and have a hard time finding the right size; and that I would only find bulk quantities, and have to buy a bunch of stoppers I didn't need and spend a lot more. I was very pleasantly surprised to find not only a variety of sizes, but also to be able to purchase one stopper for slightly over a dollar. Shipping was free, and I got it super quick. Product was exactly what was advertised. I couldn't be happier with this purchase and this company.

Happy in Kentucky!
Ordered 25 rubber stoppers to be used as inserts for screw holes in my rubber curb ramps at the end of my driveway, (wanted to keep water and debris out). First off, I had no idea what I was going to use, but after a bit of research I found this company, and realized that they had the perfect solution. Based on what I had found earlier on the web for covering the holes, the cost of what I found was outrageous! When I saw the price of these...and when bought in bulk, (I needed 24, but bought 25 to save over 15%) that sealed the deal. The order was quickly shipped and well packaged. I was very pleased with the quality of the stoppers, and best of all they worked perfectly! Great company!

Fine Rubber Stoppers - One piece Orders Available
WidgetCo allows one piece orders through their system; this is getting harder and harder to find. Very nice option for private use of materials instead of treating all Customers like a manufacturing plant.

Rubber stopper — #4 size
I ordered a #4 rubber stopper. When it arrived, I measured it carefully, and indeed it was a #4 rubber stopper. Is this a great country or what!

#4 Rubber Stoppers
I got these as a replacement stopper for an old Swiss M32 canteen to replace the old, moldy cork stopper. Fits perfect and works great. Great service and fast shipping. Glad I found your site.
