A Round Tuit is a round piece of thin rubber used to grip jar lids to unloosen them. I have one in my kitchen drawer.
When I was younger (a long time ago) my wife and I worked with a youth group. She sewed up some Round To Its and we gave them to the kids whenever they were going to get round to it. Progress on the wiring for the layout and train barn is progressing as I get round to it!

This reminds me of Round Tuits I’ve always wanted one, but I’ve never managed to get a Round Tuit. Les
Hi Les, Sheesh that can be fixed.

We’ve had them fo several years - almost five - on the RhB Forum. 
HaHaHa…
No seriously!
I saw china plates like that being sold in Scotland many years ago.
