This is frankly the me..e, do not trust the Japanese manufacture mention; because in my opinion it rather from the depths of Asia. (thickness 0.3mm so old technology). The glass was already dirty on the face to be in contact with the glass of my One +, so unusable. So by searching the forums I found the rare bird, tempered glass protective CaseBase, no longer being distributed on Amazon.com; I was able to buy it on the website of Amazon.uk and free shipping.
