Atomic Number 24/7 Onnium Periodic Table Mug | Chemistry Humor

Warm coffee, late-night lab sessions, or a steady companion on the desk — this glossy ceramic mug wears a clever chemistry joke with quiet pride. The green periodic-table-inspired design reads like a badge: “My atomic number is 24/7” above a stylized ‘On — Onnium’ tile, with “Always On” below. It’s the sort of mug that sparks a smile from chemists, students, lab techs, and anyone who runs on curiosity. The shiny white finish makes the print pop, and the comfortable C-handle keeps it easy to grip during long reads or coding sprints. Practical too — safe for microwave and dishwasher use, lead- and BPA-free — so you can reach for it every morning without fuss. Available in two sizes for those who want just a quick pick-me-up or a long, slow pour-over.
