Candy Candy Postcard Letter Set (2 Types)

This is a set of Candy Candy postcards/letters that have been stored at home for a long time.
There are two sets available.
I opened each set for this listing.
One set contains 5 pairs of postcards/letters, and the other set contains 4 pairs.
There are no particularly noticeable stains, but one postcard/letter has a noticeable stain, so please check the images. (Image 9)
Also, there is a smell from being stored for a long time... please be aware of this.
The instructions for using the postcard/letter set are dated October 1998, so I believe they were released around that time. These are items that have been stored at home for a long time.
Thank you for your understanding.
Thank you very much. m(_ _)m
