I received the Water Sleeping Mask EX rather than the original formula, and I understand that the EX is the newer formula, but I did think I was going to receive the original, so that was disappointing. The ingredients are different and the EX does not work as well for me. It also says "NOT FOR SALE" on the back of the container. I like the option to have a miniature product to try, but it's disappointing to receive a different product, and to find that it isn't even supposed to be sold. If you are able to get the original water sleeping mask, though, it's a good product.
