Just simple and straightforward

Plug-in with several input options. Enought for most web WooCommerce products. In our case adding a text to personalize key rings.
Something that I really like is the option to add your own html code before/after the field, pure html+css. You can solve any output view problems with your favorite template. Also fields have their own id, then you can just play with CSS to adapt it to your favorite template in case something doesn’t fit well.
