It is a nylon rope by iPhone 11 Pro HD Macro Lens.
It is custom for iPhone 11s!
The use is super easy, just get the lens close to the object, slightly adjust the focus by leaning a little bit closer or away from the object until it got the clearest image, then just shot and take as many pictures as you can.
If you are a pro, there is no problems you can take stunning pictures.
If you are just a newbie, the macro lens is still a good start for you, why? Just take as many pictures you the insect / object is allowed, then choose the best one to show to your audience. 1 out of 10 or 20 or at most 30 will surprise you as we always did.
