Staircase shells are also known as Wentletrap shells. Wentletrap is Dutch for spiral staircase. This Herend Staircase Shell is the perfect way to bring a little bit of the sea in your home. Herend is known for its long history of producing the finest hand-painted porcelain worldwide. Herend’s trademark fishnet pattern design, which is most popular in the U.S., originated in 1858 when an artist intrigued with a Chinese plate’s fish scale design painted it onto a rooster figurine’s breast to imitate feathers. Each Herend figurine is handmade in Hungary.
