“Ex Libris minerva” Promised Neverland stamp

This is a 3D-printable stamp inspired by the mysterious “Ex Libris William Minerva” symbol from The Promised Neverland. The design features the iconic owl enclosed in a broken circle, with the Latin phrase “EX LIBRIS” above—used in the anime and manga as a secret sign of refuge and knowledge.

This literary-style stamp is perfect for marking your books, notebooks, or crafting projects. Whether you’re a fan of the series or just appreciate the classic ex libris style, this project brings a piece of The Promised Neverland into the real world.

• A high-resolution stamp plate with raised artwork (mirrored for correct stamping).
• An ergonomic handle designed for easy gripping.
• SVG file for custom edits or alternate uses.
