Karter Scientific 216V2 Rubber Stoppers, Size #11 (3-Pack)

Rachel Snow: If you want to plug a bottle (e.g., to make a water bottle rocket), you’re going to want a size 3 stopper. These worked perfectly for my needs

Dean F.: These rubber stoppers will work for stopping water from going into my pool deck railing, I just didn't measure right so I have to shave them down about a 1/8"

WN: Excellent and size is right on the money. Only needed two but it was cheaper to order the multi pack. Would highly recommend and the price is outstanding plus I will have a few spares to use as replacement if need too.

walkrdg: Bought these for a project I'm building. Pleased for the quality of shape with no ragged edges, and they're solid. Just what I needed.

mike000mike: As long as you know your sizing these are good use corks but I would use them in industrial and not food based product use. The smell was overwhelming and didn't know when they would wash off or if that would impact something like using it as a stopper in a carafe for water

Michael Roberts: Exactly as described. Good service and product.

tflf: For some reason, cork and rubber stoppers are getting hard to find. I went with these to replace two old corks from our glass wasp traps
because I could not find any cork stoppers. Product was as advertized, including dimensions, and fit the traps pretty well.
