Cuisinart Burr Grinder Plug

I have a popular kitchen coffee mill for grinding whole bean coffee. You can detach the collection bin and keep your unused coffee in it until it's time to brew. There is a nice seal around the lid of the bin, but there is a gaping hole where the ground beans enter from the mill. This little plug fits securely in place to help maintain freshness.

Yes, I know you can just mill what you need and also keep the bin in the mill on your countertop. This is just something I find useful for my particular situation.
