The suggested measurement for these stoppers was perfect! I saved these glass dairy bottles to reuse but the plastic caps they came with all tore over time. I’m pleased with the pure gum rubber stoppers as replacements since I hand wash the bottles and I didn’t need a stopper to withstand high temperatures, so it’s nice to use a natural material. The pure gum rubber stoppers perform better than the plastic caps the bottles came with and the stoppers keep any liquid from spilling out of the bottles in transit, even when jostled or turned on their sides.
good service and cost, especially free shipping
Much better than expected.
Outstanding quality pure gum rubber stoppers.
What a deal

Pure Gum Rubber Stoppers
Recently purchased a few Vintage Glass Milk Bottles and of course they were missing the lids. I started shopping for corks large enough to use as stoppers and the local hobby stores were asking an insane price for them so decided to "Google It" and so glad I opted to do so. My search led me to WIDGETCO. Out of curiosity as to what a widget was I clicked and I was amazed at the selection and pricing this site offered. The Gum Rubber Stoppers looked like the perfect fit for "Vintage" bottles and the price was 1/3 the cost of the cork ones offered by the craft stores so I took a chance and ordered a few. I am totally elated with the look and quality. I have already told a few people about this site and plan to be a return customer.
