These are compatible replacement blades for Gillette Fusion razors. The brand is ZHISHANGS. The fourth image shows genuine Gillette Fusion 5+1 replacement blades, and these products are compatible replacements. I purchased a set of 16, but only used one blade. The holder broke, and when I asked my wife to buy a new one, she accidentally bought a different brand, so I can't use these. I am selling them. The original purchase price for the set of 16 was around ¥3,000. One blade has been used from the set of 16. I will include the box, but it will be folded for compact shipping.
