Basically, these are B5-size notebooks. The four sketchbooks are B4 size. The sketchbooks have some wrinkles and tears on the covers, but the contents are clean. One more sketchbook has been added. These are new and unused, but have been stored at home. I received these as gifts, but I won't be using them, so I'm selling them to declutter. I'm also selling puzzles, toys, etc. I will offer a discount for combined purchases. Thank you.
