Purekra 6 Pack Silicone Glass Bottle Replacement Caps, 48mm Diameter Bottle Lids Fit Stanpac & Libbey & Stock Your Home & The Dairy Shoppe Milk Glass Bottles. Reusable and Airtight Bottle Caps

I bought these for milk bottles that are from back when people used to buy milk from a dairy in glass bottles. I don't remember that even from my childhood, so they are old. I use the bottles for water and on their maiden voyage with these caps, some guy cut me off in traffic and I had to slam on my brakes, throwing the full bottle off the front seat onto the floor. Didn't spill a drop. They're pliable, so sometimes they are a little hard to stretch over the mouth of the bottle, but go on relatively easily.

Perfect fit for vintage small neck Thermos 2480. Safe replacement for original stopper #764, which may contain BPA.

Work great on glass milk bottles! Seal tight, easy to remove (though not too easy), and easy to wash.

I have some old glass milk bottles that I keep drinking water in (avoiding plastics). These fit perfectly over the top opening and don’t leak. These silicone is flexible and very long lasting. Colorful, too.

Very Good Product

I have bunch of these glass bottle and too lazy to return it to the store for a cashback.. so I decided to utilize these bottles for my home and these caps really fit and can replace the previous origin caps that wasn't reusable.

The silicone pliability is a plus. They fit well and seal tightly.

I started changing over to glass from plastic. The plastic caps on my pint and quart bottles began to crack and break. Then I found these. They’re silicone. Very soft and elastic. They seal tightly. Easy on/off. They wash up nicely. A superior upgrade from what I had. Very satisfied.
