"Stria" is a collection of porcelain forms: a plate with a groove that follows the outline of the plate and three elements, each of which has a little foot that hooks onto the groove. The foot of the plate itself also fits into the groove thus allowing stacking of several plates together when they are not in use.
In case food with sauce is served, the groove will prevent liquid from flowing out from the plate. Yet the groove can be closed with a colored polyurethane stripe if dry food is served and just a flat surface is needed. Small liquid dishes can be served in the spoon or in the bowl. The borders allow dividing the surface of the plate in zones for visual separation of different parts of the course.
