If you are ordering from within the EU, there is no invoice or price tag included in the package when it is delivered, only the required shipping label which will be attached to the box.
If you would like to have the invoice for your order, you can use the order confirmation email (which you received shortly after purchase) as a receipt/invoice.
If you are ordering from outside the EU, we will not be able to ship your order as a gift, as we need to follow regulations and provide the relevant customs information correctly. If the proper information is not provided, your package may be blocked, destroyed, or returned to us and we risk being prohibited from shipping to your country.
