So I have these in green (to cosplay a natural-ish Misty from Pokemon) and loved them so much, I decided to get them in brown to cosplay Go-Go Tomago from Big Hero 6. They blend in just perfectly with my dark brown/black eyes (still vibrant enough to see the color), and you really can't fault the enlargement - it's crazy! Comfort and all are there, as you'd expect with Vassen :3 As they're so large you might get a slight halo effect depending on your iris, but it's pretty cool.
One note though: for some people it might take some time to get used to the pattern, as there's hardly a limbal ring. Think "natural dolly enlargement" :)
Candylens doesn't disappoint of course with their service; communication and all that is top notch. Thanks guys <3
