Sealing a dog treat jar with seal tape?

My wife and I got a really nice Mackenzie-Childs dog treat jar that looks just like this:


And the lid is just metal and sits on glass of the jar… I know they make cookie jars and what not that have that little silicone strip to seal in the lid on the rim of the jar… short of buying a new cheaper jar, is there like a “silicone seal tape” that would be kinda like a weatherstripping? You know, like a wiper blade material that would seal the lid…

I can’t for the life of me think of the words to google to find such a product because all I keep coming up with is jam jar seals and all kinds of sealing tape.

Thanks.
