Sizes vary. Please understand that these are fabric scraps. You can check the thickness in the photos, but please feel free to ask any questions or request combined purchases in the comments. The ballpoint pen in the size photo can be used as a reference, but I can also measure the pieces. Please comment if you'd like me to. They will be shipped in a compact package, so they may be slightly rolled or folded for packing. Thank you for your understanding regarding shipping costs and the compact packaging.
