Hello, @filmguerilla,
Alright, I have understood your issue, and thanks for letting us know that you are not using the single product builder.
Now, to solve your issue first you have to enable the social share from the Dashboard >> XSTORE >> Theme Options >> WooCommerce >> Single Product Page >> Single Product Layout check this image: https://postimg.cc/vDrDTHTm
Then to make the icon black and bigger you need to add the custom CSS code in the Dashboard >> XSTORE >> Theme Options >> Theme Custom CSS >> Global like you see in this image: https://postimg.cc/7b58tB8r
Here is the CSS code.
.single-product .product-share .menu-social-icons.icons-filled li a i {
background-color: #000 !important;
font-size: 20px !important;
}
