Some kind of ancient life form?

Firstly, please look at this picture. What it looks like?

My daughter said "Is this some kind of ancient life form?".

What it looks like for you?

Yes, it does look like ancient life form. Some kind of old insect?

Of course this is not ancient life form. 

Other pictures follows.

Then, this is what it become.

And this is how to use it.

Could you guess what it was?

One of my collegue had trouble with his very slipply mont-bell sholder strap, so he consulted me if I could attach leather pad to make it stop slipping.

With this lether Slip-Stop-pad, I designed with two points:

1. Should be easily detachable.

2. Should not cover "mont-bell" logo.

I hope my collegue like it and work as it designed. :)
