I got an email from Dread a little while ago to say they're looking at a new keyring. I could certainly do with a replacement as mine's looking worse for wear.
Keyrings were available many moons ago (mine's looking a bit tatty now, once one of the HalfPints used it for undisclosed purposes). The new lot seem to do keyrings, so I'm sure we'll see keyrings available soon. Although if it's just a smiley covered in cheap plastic...
