The Creality K9 Clear Rectangle Crystal – 50 × 50 × 80mm, Pack of 4 is a premium set of optical-grade K9 glass blanks designed for 3D inner laser engraving, personalised gifts and professional display pieces. Each rectangular crystal block offers excellent transparency and a smooth, polished finish, helping engraved images, text, logos and detailed designs appear sharp and clearly visible within the crystal.

Made from high-hardness K9 glass, these blanks are durable, scratch resistant and designed to provide a clean engraving surface with minimal internal imperfections. Their larger 50 × 50 × 80mm format makes them well suited to vertical portraits, commemorative designs, corporate awards, memorial pieces, art collectibles and illuminated crystal displays.

This pack includes four clear rectangular crystal blanks and is suitable for use with compatible UV inner engraving systems, 3D subsurface laser engravers and selected laser machines designed for crystal engraving. Each piece has polished faces and a professional finish, making it ready for custom engraving and presentation.

For best results, handle the crystals carefully and clean them with a soft microfibre cloth and a small amount of rubbing alcohol to remove fingerprints and dust before engraving.
