I got these to replace some missing stoppers and they are perfect. Since they are tapered, I didn't have to worry about an exact size fit. They push in easily until the fit the diameter of the hole on the lid. They are exactly what I hoped for when I placed the order. The price is good for 8 stoppers.

Perfect fit into a 3/8 inch ID silicone tube, for a secure stopper experience. These are very nicely made, precision size silicone stoppers, good for any use that requires these dimensions in tubing or glassware in particular. Easy to insert and remove, but they don't come out until you want them to. Perfect.
