It does have a function. The original intention was to be a coat extender for kids who couldn't reach the adults' coat hangers, and secondly a toy.

Don’t know how to explain a work of art.

I have an old big monkey and I just love him! I like to dress him up.

The nail will go in easily IF you aim it between the two strands of rubber. Make sure you don't have the strands twisted. A bright light will help you see if they're straight or not. You can also do a preliminary probe with a dull needle (like a tapestry needle). Avoid just forcing the nail in through the rubber itself because that will weaken it. Once the nail is in, the tension of the rubber loop will hold it in place. Nothing else is needed. The factory has a metal rod secured to the work table for looping the string on. Those of us at home can use a doorknob or some other thing that will not move. You might need someone else to hold a flashlight so you can see what you're doing. I've done a lot of these and I still can't do it as quickly as they do in the factory.

I took needle nose tool and backed my nails out through the side hole of the arm and out the top. I reused the old nails. This is probably too late.

The o ring will hold the nail in place if the sharp part goes down in the wood.

The Hay crates have sides of equal height which is, at least for my use case, a huge difference.
