Gems Selfie Stick New Sealed Box Telescoping and 50 similar items

This is a "selfie stick", new in a sealed box. It is a "GEMS" brand , made in China.. The box outside does not state how long the telescoping handle can extend. The back lists the following features: Take selfie photos from a distance with a telescoping handle and remote shutter. (The box does not state how long the telescoping handle can extend); Plug and play operation, uses 3.5mm audio jack to connect your device; Universal design fits a variety of devices between 2.5 to 3 inches wide; No battery or app needed. I have not opened the box and do not know if one has to buy or have any items, such as the audio jack. I am technologically challenged and have basically stopped taking pictures since they became digital. I am downsizing and hope someone can use this selfie stick. Non-smoking household.
