Our feathers include an invoice and this alone suffices as a document that proves your purchase from us as being legal and ethical. A certificate isn't required in most situations but feel free to order certificate/s from us at anytime, for any reason. Each of our certificates (aka: e-Certificates) are tailored for the feather item they are connected to, as such they are most accurate and authentic. To order a printable e-Certificate (@ A$10 flat fee per certificate) - please complete this order form. Only one certificate per item is issued, as such - for example: 3 separate items, each requiring a certificate will cost $30 ($10 x 3) and we will issue our customer three separate certificates. This also allows our customer to formally distribute feather items to multiple people and keep the invoice/s confidential. Price of item isn't shown on the e-Certificate. Note: One item doesn't necessarily mean one feather. An item is every feather showing in the photo and/or the feather quantity assigned with the unique item code, per line on the invoice. As such, one certificate (for $10) will represent every feather that's connected to the item code and its relevant photo.
