I will start out with the good, the binder looks amazing and "the binder" functions well. Now for the blatant misleading and outright lie, the description says, "400 Side Loading Pockets", this is not correct and is the SOLE reason for purchasing the binder. Every sleeve has top loading pockets, and any avid collector will tell you top loading sleeves are absolute garbage. I do not understand why a company would lie and mislead their customers, we add to our collections, and you would think repeat customers would be a priority, clearly not with IOCOCEE. I will not return the binder, but I will not use it for the Master Set that it was initially intended for. DO BETTER.
