3 sizes in package (S, M, L) [SEP] Love the masks, but I did not like that it was not specified that they are three different sizes.  They are basically one each Small, Medium and Large.  This is great if you have kids.  I don't. I gave one to my young niece.<br /><br />They took forever to get here so I feared they got lost or stolen in the mail.  After a call to the USPS, they magically arrived the next day!  I would recommend them.
