PVC Chinese-Style Large Bookmark
Working principle: The lens surface is covered with tiny ring-shaped grooves. These concentric microstructures are equivalent to countless tiny convex lenses that can effectively focus and refract light to form clear, magnified images. Product features: Ultra-thin design: as thin as 0.45mm, light and portable HD magnification: clear image and wide field of view High safety: not easy to scratch or break, safer to use High transmittance: no reading stress, comfortable visual experience Supports customization: size, shape and thickness can all be customized on demand Why choose Yuying Optics: as a source manufacturer, Yuying has independent design, mold processing and full-process production capabilities, supports OEM/ODM, delivers fast, and offers stable quality.
