Unopened package containing 4 replacement blades with 5 blades each. Purchased on Amazon. - Quantity: 4 blades per pack x 3 sets + bonus - Blade type: 5 blades - Package: Unopened Thank you for viewing. I purchased these on Amazon, believing them to be genuine products, but they turned out to be compatible replacements. They are compatible with Gillette Fusion and ProGlide razors. The sharpness is not nearly as good as the genuine blades, so please purchase these only if you are okay with that. *Regarding the bonus* I will include a bonus item that has been opened, with only one of the 4 blades used. One blade was removed from the holder for my own use, and the remaining blades are unused and have not been touched, but please understand that the package has been opened. Please comment if you do not want the bonus item.
