After a few weeks of driving for driving for rideshare services I learned (the hard way) that youreally need to have a barf bag at the ready, because you never know when you'll need one.

I ended up purchasing a dozen Dynarex 4707 emesis bags, which include a ring with mounting notches. This holder allows me to keep one mounted in my car in a location that is out of sight, but can be accessed quickly.

Optional: Sand down the attachment nubs

Depending on how you'll be mounting the holder, you might want to sand down the attachment nubs a bit to make the bag release more easily.

Mount using M3 screws and bolts

You can find them at any hardware store. Washers are also probably a good idea.

In my case, I attached the holder inside the lid of my car's center console. This required partially disassembling the console and drilling holes using the holder as a template.
