I ordered these for use in my soon to be new bathroom, (ok eventually to be new).  It will either be used above my walk in shower or as a back splash to the sink. They arrived quickly and in good condition. They are as advertised. Very thin, in packs of 12 sheets. They are definitely grayish rather than white, with a darker gray "grout" - note the photo with the white cardboard disc next to the product for color reference. I personally was looking for that so I am very happy and think they will go well with my gray-white color scheme, with pops of coral and seagrass! I hope they adhere well and hold up in a moist environment! I will have to add to this review once I find out!
