Fashion and Travel Accessories Design Smile Business card holder by Ari Korolainen Smile is a simple business card holder with an interactive function. It is not just a regular holder for your business cards, but also an icebreaker, a fun conversation starter with a plain yet practical design. Pulling the band makes the cards automatically pop out, and the holder is closed again by putting the cards back in. The mechanism is simple yet convenient in its ease of use. The holder is made of durable recycled leather, and is available in several colors.
