# Custom fields
The Custom field product block can be used to add additional fields to a product form. This can be used to collect more information. E.g. include a custom engraving field to let customers customize their purchase.
{% stepper %}
{% step %}
Go to **Online** **Store** > **Themes** > **Customize**
{% endstep %}
{% step %}
From the dropdown in the top bar select Product
You may want to create a new product template. If you want your custom field to show up on every product page, use the default product template. Otherwise, create a new template.
{% endstep %}
{% step %}
On the left-hand side, click **Add block** then select **Custom field**
{% endstep %}
{% step %}
Add a label and check **Enable required field** if you want to make this a mandatory field
{% endstep %}
{% step %}
Reposition the block. It’s best to place this just above the **Buy buttons** block
{% endstep %}
{% step %}
Hit **Save**
{% endstep %}
{% endstepper %}
