Prepare trading cards for grading with a focused flattening & cleaning kit. Start by wrapping the card in heat paper, then make brief, low-heat passes with the thermal pen. Sandwich the card between clear vinyl / acrylic sheets, apply even pressure with clamps or the bone folder, and allow it to cool flat. Finish by using the sponge pads to remove light dust and smudges so centering and surfaces present cleanly. Recommended for routine card care; avoid excessive heat, especially on foil, and do not use on severely damaged cards.
