Query: THE Worst Sleeves I've Ever Purchased

These are the worst cd/dvd sleeves I've ever purchased. I go through a lot of sleeves, I've probably gone through several hundred this year. I ran out of my usual sleeves and was in a rush to purchase more. I get 2 day shipping with Amazon, so gave these a try... what a mistake. They're incredibly cheap and flimsy, beyond what I expected. The sleeves I usually buy are priced the same and are made of 80g paper, so I thought I'd be getting a similar product, but that wasn't the case.
