Ceramic or porcelain made in France cups for wine? I think

I went to three thrift stores today and bought these four cups, the one in the front has a ribbing around top edge, it is only one marked, made in France, the other three have no marks and are alike and a little bigger and taller. I am using as wine, I think France and must be! They were $1.50 each, so $6.00 total, I looked for awhile on internet but did not find any like them. I like them as they are short, I sometimes knock over long stem wine glasses, especially after 4-6 glasses! haha They are kind of cute, they made my day happier!
