The Post Card 4 mobile is based on a brilliant idea by Ryusaku Kawashima. You can create your own, unique hanging mobile by complementing it with small notes, photographs, postcards, or any other memorabilia you like! Post Card mobiles were previously named Memorabilia. Handmade in Denmark, the Flensted mobiles are unique and stylish elements in home décor and public spaces. While floating in the air, the mobile catches the eye and envokes interest and creativity in both children and adults. Every Flendsted mobile is designed to constantly move with the air currents in a calm, balanced manner.
