This is a set of 7 types, with 5 sheets of each type. They are new and unused, but have been removed from their packaging for photography. Please only purchase if you understand this. The larger ones are 14cm x 10cm. The smaller ones are 10cm x 7cm or 7cm x 10cm. Please note that these are amateur measurements and may have slight errors. They will be sent in simple packaging, placed in a plastic bag together, and shipped via YuYu Mercari便 with tracking. Due to my irregular work schedule, I have set the shipping time to 4-7 days, but I will ship them as soon as they are ready. Thank you for your understanding m(__)m
