Seria Packing Cardboard Sheets, Postcard Size, Set of 3, ③

?Seria (100mm x 148mm) Cardboard Packing Sheets, Postcard Size (100mm x 148mm), 16 Sheets x 3 Sets

These were purchased as stock when I was collecting raw photos and cheki.
I am selling them because I have too much stock and it's difficult to store.
Combinations with postcard size are also possible within the 3 sets, so please consider them together. (e.g., 1 set of postcards, 2 sets of trading cards, etc.)
