Hi,

To do this you will need to copy the file woodmart/woocommerce/content-product-standard.php to the child theme and put this line before all the code

<div class="woodmart-product-wrapper">

and this to the end of the file

</div>

Also, add this code snippet to the Custom CSS area in Theme Settings

.product .woodmart-product-wrapper {
	border: 1px solid #efefef;
	padding-bottom: 20px;
}

Regards
