This is a listing for a Japanese-made cleaning solution that is no longer in production and therefore difficult to obtain. Even with only 10ml, a typical use requires only 3-5 drops per cleaning, so it should last for several years. It is 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. *If you would like to purchase multiple items, please leave a comment. We will discount the shipping cost, excluding the commission. Sundai, Kawaijuku, Yozemi, Toshin
