I love my blank Moxie PRN book. The size is perfect as it fits in my jacket pocket, but is still large enough to have space for what I want to write. Other nurses I work with want to buy one for themselves when they see how convenient it is. I find it easiest to clean by using isopropyl alcohol or purple wipes and then get it hatever remaining residue off at home with soap and water to make get it back to full clean. I bought expo wet erase markers and they have held up really well, almost too well. I may try sharpies and see if they are easier to remove. All in all I love this little book.
