This set contains 24 colors, but one sheet of yellow has been partially used. 18 x 18 I try to inspect items carefully, but I am a private seller, so there may be oversights. Please refrain from purchasing if you cannot accept this. I apologize for being blunt, but thank you for your understanding. The shooting props are not included. Stored at home. I will compress the item to within 3 cm for shipping. Please be sure to read the above product description and profile. By clicking the purchase button, you are considered to have agreed to these terms.
