I love scrapbooking and stamping/card making. I was also an elementary teacher. As far as something that would have been good in the classroom, these are amazing. They are not overly sharp so you don't have to worry about little fingers getting hurt with these. As a teacher, these get 5 stars.
As a paper crafter, they fall a bit short. On thinner papers, such as notebook paper or construction paper, these cut beautifully. However, when cutting cardstock (a much thicker paper) they seem to have an exceedingly hard time getting through the paper without leaving pieces that are not fully cut. As a result, you end up having to re-cut and the lines do not look as sharp or clean. I wish I had known that before buying them but at least I can still use them on thinner papers. So, if you are looking for some nice scissors for cardstock, please find something else.
Also, this same set is available from another seller on Amazon for a bit cheaper (at the moment I write this they are $7 cheaper) and the shipping is free on that set as well. They are labeled as "Rotating Wood Scissor Organizer With 18 Assorted Kraft Edger Scissors" but it appears to be the same set by the same manufacturer with the same number of scissors in the set.
Here's hoping you have better luck than I did! :)
