Thank you for looking. This is a pencil case/pouch released by Sanrio. It can be used on both sides as it is reversible. It is no longer sold, so it is considered a rare item. It is authentic. It was used as a pencil case for several months, so there are stains (pen ink), slight scuffs, and signs of use in the areas shown in the photos. The inside of the pencil case has some pen tip marks as shown in the photos, but it is relatively clean.
