Holotapes are small, rectangular storage devices with a retro-futuristic design, featuring a sleek metallic casing with rounded corners and a prominent playback button. The surface is slightly weathered, showing minor scratches and scuffs from post-apocalyptic use, with a glossy finish that reflects the dim light of the wasteland. Each tape has a unique label, often handwritten or printed in a faded, vintage font, indicating its content or origin.
