They're from the brand GEO.
Diameter: 14.0 mm, they looks natural.
How comfortable? 5/5
Left : without lens (and without make-up, lol) - Right : With lens
(Pssss, you've got the link of my Weibo just under!)
They're very comfortable, like every pair from GEO.
I love them a lot even if i think that they looks better on Amiaya than me. haha
