If you run across these, pick up a few.(limited time edition). They are a flexible hard rubber, and palm sized for a variety of uses. Being food grade, they seal well, and seem to be very durable. They would do well for a fire starting kit or tool caddy, jerky jar or soap box for pack use. Tea or coffee canister, sugar bowl. Nice little containers. I have about half a dozen so far, and have put them to work. Enjoy.
I've been using these on jobsites for a few weeks. They are a lot more durable than peanut butter jars (plastic or glass)
I thought that they were an ET attractant . On with the subject , I save anything with a potential uses . Seems stupid to throw something I've paid for , in the trash, simply because it's empty temporarily .
