This is a set of 10 sheets x 3. I have opened the package to check the number of sheets, but they are unused. Regarding the size, it is as shown in the second image on the website. I have not remeasured them. I plan to ship these from the post office, so shipping will be on weekdays. There may be times when it takes longer than the specified number of days to ship. Thank you for your understanding. I have other items for sale, so please take a look if you'd like.
