Hello Kitty message cards. These were received as shareholder benefits. (I remember it being around 2006-2012) They have been stored at home for a long time. There is some age-related deterioration, such as slight soiling. I have taken pictures of the front and back of all the cards, so please check them carefully. The bonus card has noticeable stains on the back (see the last photo). #Sanrio #NotForSale #MessageCards #ShareholderBenefits #HelloKitty #Kitty #Postcards
