I'm selling this item because I bought it but didn't use it. It's sold for around 3,400 yen on Amazon, etc. The items included are everything in the box. There is a simple instruction manual (English and Chinese). ■ Excerpt from the product description: 【4-in-1 Smartphone Lens Set】 This is a monocular smartphone telephoto lens recommended for live performances! Compatible with single and dual cameras, it comes with 4 types of external smartphone lenses, making it a compact and portable smartphone photography set that's easy to attach and allows for authentic photography. ★ With the smartphone monocular telephoto lens, the image quality won't degrade even when taking pictures of distant scenery. It has evolved from BaK7 material to high-grade prism material Bak4. This greatly improves color reproduction. Also, by adopting multi-coating optical lenses, you can clearly see your favorite performer's expressions. (Adjust the focus ring slowly and align the focus.) 【Three ways to use it】 1. Use it as a monocular. The soft silicone eye cup is gentle on the eyes. 2. Connect it to your smartphone. Just clip it onto your phone, and you can see your favorite performer's movements clearly on your smartphone's large screen instead of a small eyepiece. 3. Attach the included tripod and use it as a telescope. You can place it on a table during camping for bird watching or landscape viewing. 【Condition】New. There is a dent on a part of the box. A5
