100 Pack DocU-Sleeves 8.5 x 11 Inch - Self-Adhesive VELCRO & Omni-Stick Backing for Documents, Files and Presentations - Perfect for Office, School and Home Organization

The durability and sturdiness is awesome.These things are brittle AF. 2/3 of the $80 box showed up with broken corners and little pieces of plastic in the sleeves.Don't be cheap like me... get the 3M sleeves. They are far superior.Loved the versatility and durability of this product. But very hard to load documents into the sleeve - especially if it has any type of humidity in the document.My only complaint is you have to add extra Velcro in order for it to stay put on a cloth surface. I added quite a bit and some still fell. Unfortunately, if it lands on it's corner, it chips.Arrived on time, but I ordered the wrong item. I will use this for another document. This order also came with a order book and note pad. Thank you !!These are the best product of this type that I have found: bar-none & I have used them for many years now for many projects. I carry a full calendar year with me in my briefcase at all times to pencil appoints & events scheduled. I strongly recommend them and they last several years before needing replaced. I use them constantly.I am a classroom teacher and I slip my seating charts into these. I also use them for documenting daily homework, before I take it to my gradebook and enter scores or completion points. I use a dry erase marker or overhead marker to do this. It makes checking for homework quick and easy.This is great for holding certificates, it is light and i have been using this for business training.
