12001EA Warehouse Broom

This broom is listed as having a weight of 0.042 ounces or 1.19 grams. Clearly this is wrong so what is the real wieght?

Is this a good outdoor broom? Like deck, chicken coop, walkway, etc. I need a relatively stiff broom, not a softer inside broom.

If broken down could most of the broom be composted?

Diameter of the handle?
