Hello,
There is no option in Theme Settings available.
But you can apply a trick by using the following Custom CSS.
For single product:
.single-product h1.product_title.wd-entities-title::after {
content: "100% solid wood";
font-size: 15px;
display: block;
padding-top: 10px;
}
Otherwise, it requires Customizations.
For the Shop page:
.product-grid-item .wd-entities-title::after {
content: "100% solid wood";
display: block;
font-size: 13px;
padding-top: 10px;
}
Best Regards
