This is stationery featuring a design of Hello Kitty as a marimo (algae ball). It comes in a set of 12 sheets, with 5 sets (60 sheets total). It has been stored for a long time, but it is unused. If you would like to add or reduce the number of sheets, I will accommodate your request as much as possible. I also have several other stationery and letter sets for sale, so if you would like to purchase them together, I can offer a discount on shipping costs. Thank you for looking.
