Crystal - by Nicolas Nikolakopoulos

Crystal is the mold conceived by Nicolas Nikolakopoulos together with Martellato designers. The idea came from the desire to create a shape that can be composed and is perfectly adapted to different creativity.

Crystal is one of the VIP line praline, for which Nicolas Nikolakopoulos is ambassador together with other master chocolatiers on the international scene.
