I purchased this "Card & Envelope Coloring Book" in the UK. Out of the 24 cards & envelopes, I only used one card. 24 envelopes, 24 stickers, and 23 cards are unused. You can detach along the dotted lines to create cards and envelopes. I love this kind of detailed work, but I don't have much time, so I'm going to let it go. I hope someone who enjoys it will use it!
