MYTREX PROVE MT-PV22B I received an unopened item but I am selling it because I have no opportunity to use it. The box has scratches and dirt. I have not inspected or checked the operation after opening. Please purchase only if you understand the current condition. If there is a problem, please contact the manufacturer. Recently, there have been many people who request compensation after purchase. We cannot provide compensation, so please read the description carefully before considering. Free shipping. To minimize the shipping size, the item will be shipped with only cushioning material (bubble wrap) wrapped around the product box (see photo 9). Please note that this will be a simple packaging. If there is anyone who can make use of it, please consider it.
