My husband and I both love the Rollabind system.
A lot of the managers in his company have purchased the system through a company called Levenger's. They call it by another name, but it's the rollabind system. My husband uses his notebook every day, including on Sundays to take notes in church.
You can adjust the distance between the holes, and can punch them where you wish.
If you have pages coming out, you need to go up a size in your discs. If you're a member of the Fan Club, you've seen my tag book called "Memories of a Friend". Well, I kept losing a page and DH is the one who made me aware that I needed larger discs. I changed them and haven't had any problems.
I use the medium discs the most. The size of the paper doesn't matter. What matters is how many pages your putting in it.
And they do wrap all the way around! It's great!
I like the desktop version better, too, because of being able to do more pages at once. The cardstock is fine in it.
HTH! Can't wait to see what you create!
