This plugin adds a “Duplicate Attribute” page under Products in the WordPress admin, allowing you to:
<ul>
<li>Duplicate WooCommerce global product attributes</li>
<li>Copy all attribute settings (name, slug, type, order by, visibility)</li>
<li>Copy all attribute terms in the same order</li>
<li>Copy all term meta (e.g. color preview codes, custom fields)</li>
<li>Preserve parent/child hierarchy for terms</li>
</ul>
Perfect if you need to quickly replicate existing attribute taxonomies for new products or stores.

This is an extension for WooCommerce that will show your custom product attributes on the single product page above the “Add to cart” button instead of in the “Additional Information” tab. Your product attributes will also be displayed at several other locations, including on order emails. See the full list, below. This plugin does NOT affect nor include attributes which are used for Variations.
Your product attributes will also be displayed at these locations (with option to turn them off):
<ul>
<li>Cart page</li>
<li>View Order page on front end for customers</li>
<li>Emails that goes to the customer, including:
<ul>
<li>Receipt (Order Processing) email that goes to the customer</li>
<li>Order Complete email that goes to the customer</li>
<li>Customer Invoice email</li>
</ul>
</li>
<li>New Order email that goes to the administrator</li>
<li>Admin Order Details page on the back end, under Order Items</li>
<li>Grouped product page</li>
