Blank on both sides! I'm selling postcard-sized color paper! There are 346 sheets! These are blank, without a space to write a postal code. They are not as thick or strong as postcards sold at the post office. The number of sheets varies depending on the color. I do not offer individual sales. Both sides have a smooth texture, but the top four rows have a different material. Please check the photos. From the bottom right: White: 6 sheets Ocher: 49 sheets Salmon pink: 1 sheet Light gray: 9 sheets Light navy: 19 sheets Light brown: 13 sheets Gray: 1 sheet Pink: 5 sheets Red: 7 sheets Light green: 18 sheets Dark green: 4 sheets Light brown (both sides have a stone-like pattern and a slightly rough texture): 50 sheets Brown (one side has a slightly washi paper-like texture with thin horizontal lines): 92 sheets Orange (one side has a slightly washi paper-like texture with thin horizontal lines): 24 sheets Red (one side has a slightly washi paper-like texture with thin horizontal lines): 48 sheets You can use them for things like illustrated letters, or as cut-out paper, and even for birthday cards. If you want to write a lot and need a lot of sheets! Please consider purchasing!
