Optical Image Drawing - Projection-based tracing on opaque materials: Uses an advanced optical lens to project image reflections so you can trace or draw on non-transparent surfaces with improved accuracy. Easy to use - No drafts required: Download the picture, place the phone on the shelf, and trace or draw more easily. Compatibility and setup - Supports phones and tablets: The bracket offers two splicing methods, simple and quick to assemble, and fits most mobile phones and tablets. Materials and quality - Resin optical lens board: Flexible and durable, not easily damaged. The coating helps reduce ghosting for clearer traces. Ideal tracing tool - Suitable for adults, beginners, and animation enthusiasts to help develop hand-eye coordination and basic drawing skills. Use scenarios - Animation practice: Transfer and trace character poses or frames to refine timing and line work. - Sketching on opaque media: Trace logos, illustrations, or design ideas on paper or other opaque surfaces. - Skill development: Regular tracing practice for beginners to build precision, control, and confidence in drawing.
