Peach Thermal Binder 

Can anyone tell me if you have to use the covers with spines attached, or can you simply use thermal tapes, and print your own covers, too?

Dude pull test on the pages.

Hey Ben. I'm a year late (sorry) but all you need is some thermal glue and you can make your own covers. I dislike these PVC chaps myself.

What are the main differences between this and the Peach PB200-70 model?

good
