Hello! Thank you for your review! Both our subscription plans come with an insert detailing and describing the functions, purposes, and instructions on all the sheet masks included that month. However, if a mask is purchased individually online, we provide the description of the mask online in the description box rather than in print. If you ever have questions on how to sheet mask, make sure to check out our blog post "sheet mask 101" or on our website at https://www.facetory.com/pages/korean-sheet-mask-101 . Feel free to reach out to our support team at firstname.lastname@example.org if you ever have any specific questions. We'll be more than glad to help you out!
