What do you normally do with empty cardboard boxes? Most use them for storage or simply throw them away. But, for Japanese artist Monomi Ohno, they're the building material for her sculptures, which have become a buzz on social media. /Instagram Photo via @monamincb

Ohno studied art and when she decided to specialize in 3D animation, she tried practicing her 3D modeling skills with the empty Amazon boxes laying around her place. /Instagram Photo via @monamincb

That began her career as an artist. Now she can make almost anything from cardboard, including outfits, popular animated characters and even food. /Instagram Photo via @monamincb

Some of her works are quite large in scale, while others show her attention to detail. /Instagram Photo via @monamincb
