Strathmore 500 Series Charcoal Pad, Assorted Tints, 18"x24" Wire Bound, 24 Sheets

The description says this paper is white and then says it is assorted tints.

Can you please break down the numbers of paper by color in that assortment. I need 4 blacks, 4 grey and 12 whites. Will I find that quantity in that package> Please let me know ASAP because I am a serious buyer

What color are the pages, black, white, or an assortment? Thank you.

Does this work with other mediums besides charcoal?
