Unit group Orange Caramel Nana is showing off her triangular kimbap concept in her new photo.

On April 13th Nana posted a selfie on her Twitter along with the words, "Triangular Kimbap & Kimchi & Nana."

In the photo, Nana is seen sporting a headband with a 3-sided kimbap and kimchi. This cute singer showed closed her eyes and pointed out her triangular kimbap headband, and showed off her youthful charm.

Orange Caramel starred in the April 13th broadcast of SBS "Inkigayo," who then appeared onstage wearing 3-sided kimbap attire. Their one-piece dresses were in the form of a triangular kimbap shape, and were wittily labeled 'Tuna Mayo' and 'Kimchi Tuna.' They also sported cup ramen and canned ham on their heads, showing off their 4D fashion.

Orange Caramel is currently a hot ticket item as they promote their new song "Catallena."
