Original Chocolate Sea Shells Chocolaterie Guylian was created in 1967 by Guy & Liliane who joined their names by passion for chocolate and love. They created for the first time chocolate in the shape of seashells. Today, Guylian Original Sea Shells are still made with 100% pure cocoa butter and filled with the signature hazelnut praliné, made with roasted hazelnuts in copper kettles following the original recipe of the founders.
