Vintage Luminarc France drinking glass or cup with handle made of cobalt blue glass, four pieces

Funny these big ears of the cups. Handy to hold too! It has France in it with a number, which is why we think this is Luminarc, because Arcoroc always has got their name marked in it.
They look like new.

Size: 3inch x 3.7inch / 7.5cm x 9.3cm

Set of four cups.
