I purchased these write and wipe pockets for my children to do some practice work over the summer. The plastic is quite durable, yet seems to wipe away very nicely without leaving a lot of smudging and smearing from the leftover marker residue. The pockets were large enough for me to print up sheets in a larger size, and still be able to slip into the pockets without catching or becoming rippled or folded upon inserting. The markers that it came with were okay, but I did purchase some additional dry erase markers, which were also compatible with the write and wipe pockets as well. The markers with it did have small erasers on them, which is nice and works well when you have multiple children who seem to want to fight over who gets to erase everything. It made each one feel independent and they love having control over their own write and wipe pockets. I also love that they come in different colors, which allows us to distinguish who has which and color code them to each child so no one has to question which one they are going to use. Overall, it was a great purchase, and the price drop really made it possible for me to get them. This allows my kids to practice math, English, or even handwriting, so that they are better prepared to face the next school year when it begins. I would recommend picking up a set and trying them out for yourself.
