Enlarge slider arrow buttons

Hey guys, I think that the slider arrow buttons are a bit too small and I was looking to enlarge them and move them a little further up and to the left on the slider.

How can I do this?

Thank-you

 

Hello,

For this Paste this code in Custom CSS
Appearance > Theme Option > Styling Option > Custom CSS

Code:

.flex-direction-nav li a {
width: 62px;
height: 95px;
}
.flexslider .flex-direction-nav li .flex-next {
right: 230px;
}
 .flexslider .flex-direction-nav li .flex-prev {
right: 293px;
}

Note: Adjust width, height and right position according to your requirement.
