Thank you for viewing. This is a vocabulary book that I no longer use. Four of them come with red and green sheets. One is a water-resistant vocabulary book (this does not necessarily mean it is waterproof). When shipping, I will remove the rings and ship them separately to reduce the thickness. Please understand. Although they are new and unused, they have been stored at home, so please refrain from purchasing if you are sensitive to this. Returns are not accepted after purchase.
