The straight pine boxes are built with the whole frame (sides and ends) in pine and the bottom in poplar wood. According to their size we distinguish them in:
Squares. The smallest of the house, ideal for packaging delicate and high value-added products such as shrimp.
Ostreiras. Medium size. Generally used for packaging oysters, sea urchins and barnacles.
Gabarras. Large capacity. Ideal for shellfish of large volume or resistant shells.
