Ring thingy?

Anyone have any idea as to where I can buy a Plastic Ring Thingy that you insert on Ring to make it smaller?
I know you can get gold/metal ones from the Jewellers but I would prefer Plastic.

My engagement Ring is driving me nuts, since loosing weight it never stays in place

Thanks

I had some from Kleeneze but they didn't work, my rings still slipped round and round.

I'm sure I've seen it in the Betterware catalogue too, what about Ebay?

I think you're better off to have the ring made smaller. I lost my wedding ring using one of those things. Fortunately I found it months later on our gravel drive (phew).

Thank you for your replies x

I had a catalogue thingy in my Sunday paper called TEMPS L there were some in there but I can't find a web site for them. £5-10p for 10
