Review on Optimize Your Filtration with Seachem's The Bag Filter Media Bag by Ebony Shaw

mesh material is strong. The material is melted along the edges to create seams. Right on the edge. I see the potential for imperfections and opening seams. The ones I have hold up well. I stuck my hand in and pushed down to see if they broke easily as I didn't want to lose the small grains I put in the bag. Anyway, it's held up well for me. A little pricey for what the product actually is so I wouldn't hesitate or feel bad if they opened up under a little pressure and had to return them. At this price I expect high quality.
