Wooden hotel key cards are another eco-conscious alternative to conventional plastic cards.  Made from various types of wood such as maple, walnut, cherry, sapele, and basswood, these cards provide a totally unique look. Each wood type offers unique characteristics: maple is known for its light color and fine texture, making it ideal for achieving a sleek, modern look; walnut provides a rich, dark hue and a striking grain pattern, evoking a sense of luxury; cherry offers a warm, reddish tone that deepens over time, adding character and warmth; sapele, with its mahogany-like appearance and durability, provides a sophisticated and robust option; while basswood is soft and light, making it perfect for intricate designs and detailed engraving.
