Simple Trash bad holder remix

I found with the original that my bag would come loose and even the hook would come loose from the seat so I created this one. Since it's thin it's easy to twist a little to open up the hook to install yet it won't come loose on it's own.

I use 2, one on each headrest post and this holds the bag in a more open position. I have been making these for family members and they love them.
