I was having a hard time finding packaging for my little coffee maker, I had a rubber packaging that no longer sealed properly, I found these silicone ones and they turned out perfectly, they seal perfectly and make it easy to open. I think they will be more durable than rubber, so I will be assured of use for many years. Very good buy.
