To begin describing this letter set, it is very UNIQUE, especially appealing to any avid letter set collectors or or someone looking for something different :D
The paper is being attached to 2 pieces of cards as can be seen in the photos. This paper measures about 15 by 10.2 inches. In the letter set, it has one card letter that has been folded nicely and this acts as a sample for you to fold the other piece of paper (15 by 10.2 inches) available in the set. That's why you see lines on the paper in the photo, it has been pre-folded by the letter set company beforehand to guide the user when folding the letter to fit in nicely into the cards attached.
In addition, the set also contains 1 more sheet of paper that measures about 11.8 by 7.8 inches and 2 envelopes that measure about 5.6 by 3.95 inches. These are great for personal collection, scrapbooking activities and other craft projects which you may have in mind.
I do registered mailing for all my items so that items that are shipped out are always trackable. Will pack this with a cardboard backing to ensure it doesnt get creased or damaged during the process of delivery.
