Hey,
Yes,of course it is. If you are not sure with the size,go to see her,nothing worst than be hesitated before the surgery. I am 10 days post op, and couldn’t decide between 340 and 375,so I went to see my surgeon again and tried the implants to double check if I made the right decision. I am so pleased to do so as I went for the bigger one and it was the best decision I could make!
