SUPPLY Ultra Premium Single Edge Razor Blades – Black Label, Precision-Crafted in Japan, 8 Refill Blades for Men’s Safety Razors

It's a good product they Amazon seems they can't deliver to my house but I get all kinds of stuff delivered to my house you tell me address was right but you tell me it isn't hard

These Supply Single Edge Blades are exactly what you'd hope for in a premium shaving system. They’re incredibly sharp right out of the box and deliver a smooth, irritation-free shave every time. I was surprised at how long each blade lasts—easily getting 5 to 7 shaves per blade, sometimes more, depending on how heavy your beard is.What really sets these blades apart is the consistency. Every blade feels just as sharp and smooth as the last, with zero tugging or unevenness. And because they're housed in a clean, easy-to-load injector, swapping them out is quick, safe, and mess-free.

These are the best razor blades I have used to date. Others left stubble but not as much as using a modern cartridge of blades does. I bought these to see if the grind angle would actually make a difference. Boy, does it!!! I shave my face and my head every day so a blade that will offer multiple close shaves is a must. So far, I have 5 shaves on a single blade and the results were the same as on shave 1. My face and head were both left completely smooth once again. I would love to get another 4 smooth shaves to bring that number to 10 totally smooth shaves.

Alright, let’s talk about this—crafted in Japan, fancy as heck, and supposedly the best thing to ever touch my face. I had high expectations, and while these blades mostly lived up to the hype, they’re not perfect. Don’t get me wrong, they’re sharp, smooth, and make shaving feel like a luxurious ritual, but there are just a couple of things that kept me from giving them a full 5-star rating.The first time I popped one of these bad boys into my razor, I expected pure shaving magic. You know, the kind of smoothness where you wonder if you ever even had facial hair to begin with. And honestly? They did a great job! The blades are incredibly sharp, giving me a close shave without needing to go over the same spot ten times like I’m sanding down a piece of wood. I didn’t get any major nicks or irritation, which is always a win.However, as I kept using them, I noticed that they don’t last as long as I expected. After a few shaves, they started to feel a little dull, which is kind of a letdown considering they’re marketed as ultra-premium. I was hoping to squeeze a bit more life out of each blade, but instead, I had to replace them more often than I would have liked.One thing I will say, though—these blades are buttery smooth when they’re fresh. The first couple of shaves are a dream, making me feel like a well-groomed gentleman straight out of a fancy cologne commercial. They also fit perfectly with my Supply razor, no fuss, no struggle.Would I buy these again? Probably! The sharpness, comfort, and smooth shave they provide are definitely worth it, but I just wish they lasted longer. If you’re looking for a premium shaving experience with minimal irritation, these blades are a solid choice—just be ready to replace them a little more often than expected. Still, a solid 4-star product that makes shaving feel like less of a hassle!

8 to 12 uses per blade with a close shave. You can’t beat them!

Okay price point but good quality razors

easy to load easy to use

I shave with straight razors, shavettes, single-edge (Artist Club, GEM, and regular injectors) razors, and double edge razors; for days when I'm in a hurry I shave with electric razors. Why am I telling you this? Because I have a lot of experience with what's called "wet shaving." Been doing it for over thirty years. These are the worst blades I've ever used. They didn't cut! I kept going over the same areas. Finally I put in a Schick blade. It worked great. I don't know who is making these special black label blades for Supply but if blades got letter grades, these would earn an F. One person's dud blade is another person's dream blade. So try a pack. Plenty of people like them. My beard was totally immune.
