12 pack derma planing razors
I am a huge fan of derma planing and was quite intrigued by this set of razors. I was curious how they'd stack up to my tried and true disposable razors hat I've been using for years. First, they look and feel pretty nice - definitely nicer than my current ones. I do wish the handles were a lil more grippy because they get slippery very easily if they get wet or if you accidentally get oil/lotion on them. There isn't any indication of how many times you can use each razor or if they're only single use. There are two different sized razors included, but I'm not sure what the smaller ones are for - I wish they'd include some instructions! Currently priced at $13.89 for 12 razors, I find the price to be too high for what you receive. They are nice razors, yes, but they are not premium quality.

Effective dermaplaning wands
These razors work really well for removing my peach fuzz. I have a fuzzy chin and hair on my knuckles that’s hard to get off with a larger razor. These come in two sizes for precision dermaplaning. I apply some jojoba oil to my skin before dermaplaning and there is no irritation. I love the frosty translucent handles, they look clean and professional. There are twelve to a pack and they come in a little box to keep them all together. These are a great value for the quality.

Fast & Easy
These work really good. I have been waxing for over 20 years and I just wanted to try something new. This set comes with two different sizes. I used the large blade for my chin and lip. And the smaller blade for my eyebrows. The handle is sturdy and not flimsy. Comes with a case. I already stuck one of each in my travel bag!

work well + good value for the pack
Finally got a chance to try these recently. They're exactly like the ones I already had, that I paid a little more for. I think these are a good value and work pretty well - not as well as the better beauty store razors, but better than like dollar tree or something. I like the size of the handle. I consider them disposable, especially if you're using with a hair identifying powder spray or oil.

A Year of Easy Smoothness
I love that this set comes with 12 razors, giving me a full year of monthly replacements. The handle feels solid and comfortable to hold, and the different sizes are handy for both facial and eyebrow use. They glide smoothly and exfoliate gently without irritating my skin. My only minor complaint is that the blades aren’t as sharp as I expected, so I have to go over an area a few times to remove all the peach fuzz. Still, for the price and convenience, it’s great value for the money and makes skincare feel fresh and polished.
