Hm, sounds like a bijou to me http://www.sakwiki.com/tiki-index.php?page=BijouBijou with Nail Cleaner was manufactured 1980-1987. Aluminum tweezers were discontinued in 1978 so probably they still had some in stock or someone replaced them...
Interesting, Ive never seen a Bijou that said 'Bijou' on it. I wonder if that's a sales model or display model.
Ahhh well that makes sense!
