A french link very similar to a Dr. Bristol, practically identical by the looks of it, and I'm pretty sure I've substituted either for the other in the past. Maybe if you look in the Dr. Bristol catagory you would have better luck finding a thinner version? It just broadens the search, but if you don't feel they are practically the same thing and only want a french link I understand, even be curious what you feel the difference is. I can't totally tell and if you mixed em up in front of me I probably wouldn't know which was which.
