This is a model that can be used for cheating or simply to place a heart-shaped sticker. If you want to use it for cheating, you may need to use a fluorescent pen color. It has space to hold a retractable heart-shaped sticker, and there is a slot at the bottom of the eraser. If you'd like, you can sell it. This is my first independently created 3D model. Please let me know if there's anything that can be improved.
