I have a lot of crochet patterns to protect so I wanted quality along with quality. Only problem I ran into was it was hard to open them up. It took a learning curve to open them quickly. The sleeves seem to be strong. Even with my struggling to open them none of them tore on the sides. I was able to put several pages in at the same time. I can see these being used any time you want to display printed work. I have used several brands and styles over the years and I like the value and quality that is shown with this product.
We had many very old (over 100 years) newspaper clipping and letters all very fragile so buying quantity was the way to go but we struggled to get the old clippings inside the protectors without doing damage to them.
I am a teacher. All of my class assignments are in these plastic sleeves. I also use them for numerous class assignments which require that the students handle my documents. Although occasionally students attempt to deface these sleeves the sleeves are surprisingly resilient. I also use them for my photography (both when I print pictures and put them in binders and when I attach them to walls for display purposes). I don't know how many boxes of these I have purchased but the value for the quality and their general usefulness keeps me coming back for more.
Primary use is neither personal nor business. They are being used by a group of Senior Citizen Volunteers at the Campbell County Senior Center. The sheet protectors are being used to keep music sheets clean and unwrinkled. After practicing our songs we go to nursing homes and entertain. The protectors therefor are not for my personal use and they are not being used by a business as senior volunteers are not a business. Our music sheets wear down get torn are written on and now are kept clean. We can easily change a page when we get tired of songs and insert a new sheet. Thanks!
