First of all, LOVING this site - I've done virtually no work for 3 days now! It's so nice to see pictures of toys I owned years ago.
This is a long shot but does anyone else remember Pocket Pretties? As I remember there was a series of 5 (possibly more if there were earlier/later runs) available very late 80s/very early 90s. I owned 4 of them (bought from Woolworths in the UK): they were basically plastic compacts, each with a different way of opening, and held a set of little accessories that all fitted inside the compact.
One of mine contained a set of plastic stick-on fingernails plus stickers to decorate them and I think a tiny nail file too, another had a mirror, hair slides and hair bobbles, one had a tiny Post-it pad, pen, and ink stampers. I had one other but can't quite remember what was in it, and there was one with a ballerina doll that I didn't own.
Weirdly, they were made by Sega but had nothing at all to do with video games. I've found a couple of vague references to them on Google but generally it's as though they never existed! I'm going to have a rummage round my mum's house to see if I kept mine - if I find them I'll post pics!
