Wide mesh filter bags for biomedia?

[drawman]

Just curious what people are using for a wider mesh filter bag. A lot of what is sold seems to be geared towards fine mesh for carbon, gfo, etc. I would like something that will be wider so I can shake out the detritus. I'm planning on using seachem matrix fyi. I found these produce bags at target I guess my only concern would be if there is anything that wouldn't be aquarium safe (ie dye, etc).

I've also thought about making my own out of screen top material.

Those are ok to use. They are polyester and washable.
