Please take a look at the profile. This item was purchased here, and is unused by me, but the previous seller stated that they used two sheets. There are 18 coloring postcards. I don't think there are any problems with using them, but please refrain from purchasing if you are concerned about any warping or damage. Please refrain from purchasing if you are very particular. - Title: ARABIAN DESIGNS Coloring Postcards - Number of pages: 18 out of 20 - Paper quality: [Unspecified] - Publisher: PEPIN - Country of manufacture: Netherlands Thank you for looking.
