This is a real object. It is one object. An object can be any one thing. Describe it in as much detail and remember to feel it, listen to it, smell it, see it. Remember the top and bottom and sides may be similar or they may be different. There may be an inside and outside or just one or the other. Sketching is important. Don't write out words for shapes, let all shapes appear as sketches, only use words for what you can not sketch for these object exercises.
