This set includes five blank metal cards measuring approximately 80mm x 30mm x 0.5mm, made from anodized aluminum for high strength, corrosion resistance, and durability. The cards feature rounded corners, making them resistant to folding or bending. Their surfaces are suitable for laser engraving, sublimation, stamping, and other engraving methods. Edges, cut from a large metal sheet, may require smoothing with fine sandpaper or a grinding wheel before processing. Only one side is covered with a protective film, which should be removed prior to printing or engraving; the other side may have slight abrasions from transportation and is not recommended for printing or engraving. These versatile cards are ideal for use as nameplates, door plates, trophy plaques, desk tags, label tags, serial number tags, or metal signs. The size is approximately 80mm x 30mm x 0.5mm.
