Compatibility: High-quality replacement blades compatible with 5-blade razors such as Gillette ProShield, ProGlide, and Fusion. Note: This product is not an official Gillette product, but a replacement for Gillette razors, with excellent performance and comfort. It is significantly more cost-effective than genuine products. Compatible Models: Compatible with Gillette ProGlide holders. This product only includes replacement blades. High Performance: Sharp blades provide a comfortable shave and allow for a close shave without irritating the skin. Consumable & Compatible Products: Shaver parts wear out over time and their performance decreases, so the shaver head needs to be replaced every month.
