This is a telephoto lens from ShiftCam. By attaching it to the iPhone's standard wide-angle lens (24mm), you can achieve a field of view of approximately 60mm without image degradation.
It was purchased and used for about a month, so there are some minor scuffs and scratches on the exterior.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
