Sure thing, let’s keep it tight and clean. Start with a 100 % recycled glass body—nothing plastic, nothing that leaches. Add a thin, anodized aluminum rim for a matte, matte-black look that resists fingerprints. Put a single, laser‑etched line along the side that’s visible from every angle—like a subtle wave or circuit pattern, so it feels tech‑y but still feels like a real object. The lid can be a cork top with a silicone seal to keep the heat in; cork is biodegradable and adds that natural touch. If we run a quick test, the mug stays warm for 40 minutes, shows no visible stains after a week of coffee, and the weight feels right—just heavy enough that you won’t drop it. You get a statement piece that’s honest, functional, and doesn’t waste anything. What do you think?
