Personally I would like to see how the thingy is closed (corked?).

Though there are few things I hate more than (usually senseless) videos, your product seems to be one of those things I would like to see in the hands of someone (bar the actual filling) to better understand its size, weight, etc.

Also, the carabiner is intended to be able to hang the thingy on your backpack (when it is empty), isn't it?
