This is a listing for a Japanese-made cleaning solution that is no longer in production and therefore difficult to obtain. With 10ml, and using only 3-5 drops per use, it should last for several years. Compatible with all domestic manufacturers. Recently, there have been many reports of video heads failing due to poor-quality, impure cleaning solutions from overseas. For your valuable VCR, we highly recommend using this reliable, safe, and impurity-free product. This is not for consumption. Do not use it for food. *We also accept bulk purchases.
