They lay flat, are nicely padded, my only negative would be they will absorbe water and can get torn, but I have had mine a long time and they are cheep enough to replace. I just scrub them and let them dry regularly.
These are not the pencil I remember from school--admittedly many many years ago. The pencil itself is thinner. And the lead leaves much too faint a mark on the paper. More like very hard pencils from long ago.
