I ordered these laminating pouches to use with my Purple Cows Hot and Cold Laminator Purple Cows Hot and Cold Laminator, Includes 100 3 mil Hot Pockets, Assorted Sizes (3016c). I had previously only used the pouches included when I purchased the Purple Cows Laminator. These Sparco Laminating Pouches are not as high quality as the other ones I've used. They are less expensive than other brands, which is why I purchased them. For the price, I think they are a great buy. They work quite well in my Purple Cows Laminator and I've had no problems with the items I have laminated, even after regular use with several of them. I'd purchase these laminating pouches again.
The price was great. But, you get what you pay for. The material is thin. That should have been fine, but the quality was poor. I laminated 10 important sheets. Two of them crinkled as they were going through the laminator. I have never had this problem before.
