These leaf notes are beautiful, but the adhesive is not Post-It quality. If you
use them on a single page the glue doesn't stick very well. They're fine in
books because the pages keep them stuck to the page, but overall don't rely on
them if you really need to remember something on a page. A good thing about
this though is the multiple sizes and the leaf creates a wide area to write
notes on. They also just look really cool when sticking out of a book.
I was a bit disappointed with this eraser. It's very cute and the slim profile
allows a very precise erasing, but the eraser itself is a bit abrasive and feels
cheap. Not for people who like a very smooth eraser like the Hinodewashi
Matomaru-kun, which erases like a dream.
