These are very high quality and look really good. I've been using them for my 360 cube. The cards aren't damaged, they fit 15 double sleeved cards very well, overall definitely worth it for the price.
This was a fantastic purchase. The material DS uses is very high quality. I have been playing and designing cubes for years now and always held off buying the competitors pack boxes since they all looked like they would wear down easily. The DS cube shells are durable and affordable and I felt really added to the draft experience. The guys around the table felt like they were really cracking packs and it raised the level of classiness up just a bit.
