They're sheet protectors. They are clear and don't fall apart when one inserts the sheets. Do they stick to or lift the ink off printed sheets? Too soon to tell
Having recently retired I decided to finally organize an overflowing recipe drawer. Putting all of my favorite recipes into a categorized folder was the perfect rainy day project and these sheet protectors really helped.
The clear page protectors I purchased at Staples are great and of good quality. They are for a Christmas gift project I needed urgently so I could mail my Christmas gifts for Christmas. Staples always have what I need when I need it.
