🔳 Standard Large Cork Stoppers - Size 30 by WidgetCo Review

is used for hot water thermos flasks. fits. However, it gets dark after a week of use. I suspect that it is not made for this purpose.

I spent a lot of time getting the exact dimensions of what I wanted to connect. Turns out I didn't need it. The tapered design gives you a lot of bugs. Plan to replace the wood countertop that the rubber gasket has rotted on with another one.

This cork is not a solid piece of cork, but consists of 3 layers glued together. Who knows what kind of glue they use?! I use this as a stopper for drinking water, so I'm concerned about the possibility of chemicals from the adhesive leaching into the water. In terms of fit, it's not airtight; Water still comes out when I turn the container upside down. I think a light coat of beeswax might solve this problem.

Had to send back. I needed specific dimensions for the pitcher I'm using. The website lists the dimensions I need. The dimensions of the cork sent differed from the diameter of the top by a quarter of an inch. Doesn't go with my mug.
