Mini-Postcard | The Royal Ball

This mini-postcard/mini-print was originally the backing card for the 2022 Advent Box Item, "The Royal Ball" Location Terrarium Pin. I designed this backing card to also be functional without the pin attached, and this listing is for my spare supply of cards. 

Measures A7 size (74mm x 105mm). They are half the size of a standard postcard, thus I have called them mini postcards. The reverse side has a spot for a message, address, and stamp ❤
