Do you use ring binders? If you do, this product might be just what you need.
Kyowa Film Filing Seal
Each pack comes with 2 sheets and there is 12 [or 6 pairs] stickers on each sheet.
They are made of a plasticky film making them very sturdy (won't tear) even if you have to attach it to something heavy.
For example, an entire pack of sticky notes.
