Who am I?

(The English version of the ‘Wie ben ik?’ box)

I wake up and feel the burning sun on my face. I look around and see that I am lying on the sand. My head hurts and I feel a huge bump on the back of my head. When I look up I see a large rock. Everywhere I look I see sand with an occasional tree. Where am I? I wonder and at that moment I realize that I have no idea where I am, how I got here and how I got the bump on my head. I look around again and see a large black box with a lock around it. If this box is mine, then the answers will be in here and I will eventually get home. Will you help me?

There are 2 of these boxes available.

The rental costs are € 66 a box.
