100PCS Seal Pressure Foam Self Adhesive Gasket Leak Proof Lid Lining Cap Sealing Silm Waterproof Membrane for Cosmetic Bottle Cover Liner Holder Snack Storage Container(2.7cm/1.1inch)

Works well for my salves

Worked well on my small lip balm jars. Just place in the cap and screw cap on tightly and it will seal no problem. Great price too.

It's so nice I bought it twice... cause I needed more :-)

The caps are awesome for preventing leakage. I bought mine slightly larger than the bottle opening, which I prefer. When I use my twist tops over these seals the excess material folds over the edges, without making it difficult to close the bottles. I love it 😀
