I'm not sure if anyone will be interested in these but we have a whole bag of keyrings at work. I'll go measure them on Thursday but they seem to be the common size you get. Also I'll take the plastic loops off them (thats unless you want them covered in anti drink driving messages?).
Handy for making your own keyrings? You just have to pay for the postage.
