These are aftermarket parts for the NitroFactory Gpro. I bought them two years ago and have been storing them. 【nTechFit】vg-a1 【nTechFit】LF-a1 【nTech Fit】H2-un 【nTechFit】KB-a1 These four types are included. Only sold as a set. If you don't need the box, I will discount it by 500 yen. They have only been used a few times, but they are still used items, so please understand this before purchasing.
