Supply Single-Edge Blade Refills — Black Label 8-Pack, Japanese-made, Titanium-enhanced 19°

If you use a single-edge razor or are moving away from multi-blade cartridges, these SUPPLY SE refills are built to deliver consistent, reliable edges with fast, contact-free loading. Forged in Seki City, Japan, each steel blade is thicker than typical cartridge strips and is housed in a quickload injector that both protects your hands and stores used blades for safe disposal. The slightly steeper 19-degree cutting angle and titanium surface improve sharpness and glide without requiring aggressive pressure.

How do these blades load into my SUPPLY SE razor?

Reloading is intentionally simple to make blade changes quick and hygienic. The injector tray snaps into the razor’s key slot and advances a fresh blade without you ever touching the cutting edge.

• Insert the injector key into your SUPPLY SE razor slot
• Slide the injector forward to place a new blade into the head
• Used blades lock into the tray for safe storage

What makes Japanese-made Black Label steel different?

These blades are forged in a city known for blade craftsmanship and finished to a higher thickness than common cartridge metal. The result is a firmer spine and longer edge life, giving smoother strokes and fewer micro-catches during a shave.

• Manufactured in Seki City, Japan, with traditional forging expertise
• Twice the thickness of standard cartridge strips for stability
• Titanium-enhanced face for improved edge resilience and glide

How close and comfortable will my shaves be with a 19-degree angle?

The 19° angle is intentionally a touch more aggressive than milder SE blades, designed to slice cleaner without extra passes. That steeper angle cuts hair more efficiently while the blade’s build moderates vibration and irritation.

• 19-degree geometry for a closer cut with each stroke
• Sturdy blade thickness reduces flex and tugging
• Engineered for daily use with less skin stress than many cartridge setups

What safety and disposal features are included?

The injector packaging keeps both new and spent blades contained, making swaps safer and cleanup easier. When all eight blades have been used, the tray holds them securely for straightforward recycling.

• Contact-free loading prevents finger contact with the edge
• Onboard compartment stores used blades until disposal
• Tray designed for simple recycling once empty

Who this is for: These SUPPLY SE Black Label refills are aimed at men who want a high-quality, repeatable shave — whether you’re upgrading from cartridge razors, favor a single-edge setup for daily grooming, or value Japanese-forged steel and easy, safe blade swaps. If you prefer a dependable blade that balances a closer cutting angle with stable edge performance, this eight-pack of injector refills is a practical choice for regular use.
