1. Retro frame: The frame is made of old brass or bronze metal, with fine gears, rivets and other mechanical, highlighting the retro industrial feel of the steampunk style. 2. Movable gear decoration: The temples or frames are inlaid with micro-rotatable gears to add dynamic fun and strengthen the detailed design of the "steam machinery" theme. 3. Single-sided chain or goggles structure: You can choose a single-sided hanging vintage pocket watch chain, or design it as a goggles-style shape (such as round lenses + leather straps) to enhance the immersion of role-playing. 4. Gradient lens effect: Match with brown, amber or copper-plated lenses to create a mysterious atmosphere. At the same time, the lenses can be designed as hollow carvings or engraved with steam rune patterns. 5. Comfortable wearing design: The nose pads and temples are made of lightweight materials, and soft pads are added to the inner fitting to ensure comfort for long-term party wearing.
