The story
About the Locked Pen 3D icon
A premium front-facing 3D UI icon of a locked pen, perfect for interfaces related to secure writing, protected documents, restricted editing, and privacy settings. Its clean non-isometric style fits dashboards, apps, and web products. Free to download and easy to use in modern UI design.
The Locked Pen icon is part of Thridy's isometric 3D collection: soft studio lighting, gentle shadows and a clean silhouette that stays legible from hero sections down to 48-pixel UI slots. It ships as a transparent-background PNG, so it drops into any design without masking or background removal.
Designers most often reach for it in landing pages, mobile app interfaces, presentations, infographics and social media graphics. Because the whole Thridy set shares one rendering style, the Locked Pen icon pairs cleanly with the rest of the Symbols category when you need a consistent set rather than a single image.
It is a strong fit for startups, agencies, product teams and content creators - anywhere themes like locked pen, secure writing, protected document, privacy appear in your product or content. Download it free, or request a custom variation if your project needs a different angle, color or companion icon.
