Sanrio 50th Anniversary Little Twin Stars Kiki & Lala Antibacterial Mask Case This is a set of two items as shown in the photos. They are very cute, and I bought them immediately... but I mistakenly bought them thinking they were clear files, so I am putting them up for sale. Although they are new and unused, please purchase only if you understand that they have been in someone's possession once. Please note that the price will be higher than the regular price due to shipping costs.
