Polyseal 38mm caps
I have used these before. Excellent sealing cap. I use them on 1 gallon and half gallon containers, they keep carbonation in beverages very well. They tend to tighten a bit, so I have learned not to tighten fully, otherwise they can be difficult to turn when opening. Great product!
