It worked as expected.

History works but so does science.
I have been using French mustard in a stone jar for 20 years. I loved the real cork stoppers but the fricking FDA made them change to a plastic monstrosity to be able to import. While I loved the cork stoppers and could finally order them from France I did my research and found that your #12 silicone stopper would work perfectly. It has and I will be sharing this with other Pommery mustard aficionados.

Modern meets ancient.
I have been buying Pommery mustard in the 500 gram jars for 20 years. The original cork stoppers were replaced by a plastic “thing” so it could be sold in the US due to sanitation standards. (What a crock of bureaucratic BS.) Found out recently that the Pommery company now sells original French corks as a side business. Got one and it was just a dry chunk of cork that didn’t fit worth a .... soaked it in clean water for a few days and the fit was much better but it got moldy after a month.
Did some measurements and figured a #12 stopper would work. Found your site and ordered a #12 silicone stopper. It fits and seals perfectly a 500 gm jar of Pommery mustard. Tell your marketing people to use this if they can.
Your site is great and service is awesome. THANK YOU

White #12 Silicone Stopper
Perfect company, perfect product. Scored an old glass half gallon jar/pitcher for our half n half cream to keep in the refrigerator. WidgetCo gave me the choice of cork or silicone. Exact sizing is really nice. Did I say perfect company? Yes I will be hanging onto this company for future needs.

High quality product. Very pleased with my purchase. The stoppers fit perfectly!

I have a few Eagle mason jars and was looking for a dishwasher safe stopper for them. These fit perfectly. My only suggestion is I would like to have them 1 1/2 inches
long rather than 1 inch.

Silicone Stopper for old vintage thermos of many diffrent kinds
Anyone who has the vintage Stanley A-1357B one quart wide mouth from the 1970s and 1980s that either used the non screw beige stopper this works perfect and tight no leaks; a win! This company delivers resonably within a week max and you can get cork replacment for the old Stanleys or even the vintage 1970-1990s one quarts if your missing a stopper you can get a cork one. I so advise you to check this company out. Thanks for being a replacment to the old days of the local hardware store. I just suggest you measure before you order your hole for your thermos.

Diane M, Plainfield, IL - 7/10/2017
I ordered some of each size for liquid-tight bottle stoppers. Very happy with the quality, performance. Especially appreciate the high temperature range for sterilizing, as they are used for consumable liquids. Order was processed, shipped, and received in very timely manner (OK--Texas is close to California, but they processed the order very quickly). Order was received complete and correct. NO hassles!!

Fits the bill
Perfect fit, make sure you measure everything well. I am drilling into it and adding a cabinet knob for extra panache. Wish they were also made larger. Great product.
Sue N, Washington, DC - 9/11/2015
Exact size specifications were important to me. The size was right and the quality good. I actually needed two of them and I have now ordered the another one.
