★ These are leftover materials from when I made my own parts. This product is not often listed, so it's recommended for DIY enthusiasts. Especially the thick items are rare, so they may have a high value. It's dry carbon. -------------------------------------------------- ※ Dry Carbon is made by applying resin-impregnated carbon fiber to a mold and baking it in an autoclave (a high-temperature, high-pressure oven) while applying pressure. Unnecessary resin is removed, making it light and strong. It is very costly. -------------------------------------------------- ★ Please refer to the photos for the size. (There may be errors due to the inexpensive digital calipers.) ★ The surface is matte on both sides. ★ Due to the nature of the material, the cut surfaces and the cross pattern may not be parallel or perpendicular. ★ As these are leftover materials, the cut surfaces may not be straight. ★ There may be some slight variations in thickness. ★ There may be small scratches. ★ Due to the nature of the material, there may be some slight warping. The carbon cross pattern is beautiful, so how about using it for your own creations!
