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

I am writing from the perspective of using these supply blades in an actual supply razor. I don't understand all the bad reviews from people who are using them in other razors. Let me start by saying the supply razor (I know this is not about that) is the best razor I have ever used. If you follow the exact directions there is no chance you can cut yourself. I was using their black line of blades and thought I would try these. Not sure if it is my imagination or fact, but they are worth the extra few dollars. The combination of these blades with that razor is game changing. All that said their products are amazing. They need to work on their customer service. Not so great.

The Supply Ultra Premium Blades are truly in a class of their own when it comes to shaving performance. After using these blades, I can confidently say they deliver an unparalleled shaving experience. Here’s what sets them apart:Incredibly Sharp and Smooth: These blades provide a close, smooth shave every time. They glide effortlessly over the skin, cutting through hair with precision and without tugging.Long-Lasting Durability: Each blade lasts significantly longer than others I’ve tried. Even after multiple uses, they maintain their sharpness and performance, offering excellent value.Perfect Compatibility: They work seamlessly with my Supply razor, locking in securely and staying perfectly aligned. The design ensures a consistent and safe shave every time.Skin-Friendly: I have sensitive skin, and these blades are a game-changer. No irritation, razor burn, or nicks—just a clean, comfortable shave.Premium Quality: You can tell these blades are crafted with care. The quality and attention to detail are evident in every aspect, from the packaging to their performance.Value for Money: While these are premium blades, they’re worth every penny for the quality and longevity they provide. You get what you pay for, and in this case, you get the best.If you’re serious about your shaving routine and want a blade that delivers a superior shave with comfort and precision, the Supply Ultra Premium Blades are a fantastic choice. I highly recommend them to anyone looking to elevate their shaving game!

Nice upgrade over the OG

These are definitely better than the standard blades it came with. Will buy again

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!

High quality; comfortable shave.

I love those blades. They’re so much better and cost effective over the cruddy Gillette or Harry’s razors. I pay ten bucks for eight blades and they last a total of four to five months for me (I shave every other day). Provided they never sell out and reduce quality, I’m a customer for life.

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.
