COMPLEX BOXES (PZL)
Complex boxes are a group of boxes that falls outside of the aforementioned categories. Their construction is complicated and unusual enough, that there is no sense in making a separate category. Actually, it should be called Special Boxes. They are made for a specific order. A showcase of such boxes can be seen below. Some of the pictures are just models and concepts that didn’t leave the design phase. However, we believe they can be a great inspiration. After all designing new forms of boxes is great fun!
