The Philips OneBlade QP235/50 replacement blade set provides three stainless steel blades designed to fit any OneBlade handle. Each blade features a glass micro-bead coating that reduces friction against the skin, allowing for a smoother glide during both wet and dry grooming sessions. Depending on your usage, a single blade typically lasts up to four months when used for two full shaves per week. To help you track this, a replacement indicator icon appears on the blade when it is time to swap it for a new one. This set comes in recyclable paper-based packaging, keeping the lightweight components secure and environmentally friendly.
