Cube Letter Set


These whimsical blow-up letter cubes are created by Kouichi Okamato of Kyouei Design as a new take on the traditional Japanese paper balloons. The concept is simple; you write a message on a paper cube while it’s flat, and send it using one of the supplied envelopes. The recipient then blows it up into a cube-shaped balloon to read your message.

The cubes are made of lightweight translucent origami paper and printed with faint blue lines. Each set includes one large and two small cubes, with corresponding envelopes in a sealed package.
