Custos Librorum Librarian Crest Mug 15oz – Ceramic Coffee Mug for Librarians and Book Lovers – Latin “Guardian of Books” Owl Shield Design by Lair Gadgets

This glossy ceramic mug brings quiet confidence to every sip. The white 11oz or 15oz canvas showcases a detailed owl crest on both sides — fine linework in deep charcoal and warm sepia that catches the eye without shouting. It feels reassuring in your hand: the thoughtful C-handle, the smooth shiny finish, the balanced weight. Heat your drink in the microwave, pop it in the dishwasher, and trust the colors to stay bright. For early mornings at the desk, late-night study sessions, or a slow weekend with a book, this mug adds a steady, composed presence to your routine.
