Instant purchase is okay! ^_^ This is a set of an opened item and a refill pack of 70 unopened sheets. I think I've used less than 10 sheets out of the 70 in the opened pack. I used tweezers and didn't touch them directly. I will ship them without the outer box, so please be aware of that. Please refrain from purchasing if you are concerned about the opened item or home storage. I purchased these at Olive Young in Korea around this spring.
