Pure Pack S11-16 OPP Bag Shimojima Thickness 0.03 x 110 x 160mm 100 sheets These are OPP bags purchased at a Shimojima store. They are labeled as postcard size, but they are slightly larger than a postcard, so I am selling them as I won't be using them. I will sell a set of 4 at a discounted price. They are 300 yen each if sold individually. Thank you.
