Just received them so can't say much for how long they will last, but they are made of a durable fabric it feels like. The bag is canvas type so very durable. I decided to leave them in the box for storage as it is the perfect size. It is only as big as the bags stacked next to each other.Much more substantial than bags that came with my corn hole boards. Now I have to see if they are easier to use and controlThe bags have a good feel to them when you throw. Work great!As describedThe campground that we were at had fiberglass permanent Cornhole boards installed throughout. Our little travel game bags weren’t cutting it. I came across these. They are very nice and sturdy. I’m not even remotely a professional, or an amateur for that matter, so I haven’t gotten down how to benefit from the two types of sides but my son in law uses them to benefit his game.One side slides and the other is grippy as expected. Great productThese were interesting bags. Heavier and double sided. I decided to keep them as an alternative way to play. Took them out of the box and, low and behold, 6 red stripes and 2 blue stars. So, again I wait for a replacement. Then I have to drop off the box for return. PITA. Seems it could have been avoided with better quality control.Material seems on the cheaper side, but it does work. I would definitely pay the extra 15 or so dollars for bags with better graphics on it. Just plain.Bon produitVery good for family use
