Ksenya Y056 Katya Y111 11 Extra Quality -

Then there's "11 extra quality" mentioned. The number 11 might be a rating (like out of 10) or could refer to a size. "Extra quality" suggests something of superior quality, maybe a grade or rating for the product. So the paper might be about two products (Ksenya and Katya with their codes) and the 11 extra quality associated with them.
